1. How many molecules of CO2 are the in 4.56 moles of CO2 ?


° STOIKIOMETRI °

Given

n = 4,56 moleL = 6,02 • 10²³

Ask

X = ?

Answer

To answer this question, we can use mole concept.

[tex] \Boxed {X = n \cdot L} [/tex]

So the answer

[tex] X = n \cdot L \\ X = 4,56 \cdot 6,02 \cdot 10^{23} \\ X \approx 2,75 \cdot 10^{23} [/tex]


2. How many molecules of CO2 are the in 4.56 moles of CO2 ?


Jawaban:

Thus, the number of molecules of carbon dioxide is 6.23×1022 molecules 6.23 × 10 22 molecules .


3. How many grams are in 1.2 x 10²⁴ molecules of water?​


Answer

Mass of water = 36 grams

Explanation

Molecules of water is written in formula : H₂O,

to calculate the mass of the water, we should know about realtive molecular mass of water from periodic table :

Mr H₂O = 2 x Ar H + Ar O = 2 x 1 + 16 = 18 g/mole

From Avogadro number ==>

[tex]\boxed{mole\ of\ water\ = \frac{Molecules\ number\ of \ Water}{6,02\ .\ 10^{23} } }[/tex]

mole of water = 1.2 x 10²⁴ /(6.02 x 10²³) = 1.99 mole = 2 mole

Mass of water = mole of water x Mr water = 2 mole x 18 g/mole

= 36 grams of water

4. How many grams of gas are present? 8.75 L of C2H4, at 378.3 kPa and 483 K


Bab : Perhitungan dasar kimia

Kelas : 10

Kode : 10.7.8

Kata kunci : gas, gram, tekanan, suhu, ideal

Pertanyaan :

grams of gas are

Pembahasan :

Gunakan persamaan gas ideal

PV = nRT

P = 378,3 Kpa = 3,707 atm

V = 8,75 L

R = 0,082 ltr.atm/mol.K

T = 483 K

sehingga persamaan menjadi

3,707 . 8,75 = n . 0,082 . 483

n (mol) = 0,819

gram C2H4 = n . Mr C2H4

                    = 0,819 . 28

                    = 22,9 gr

[tex]\mathbf{1.~Persamaan~Reaksi }[/tex]

Persamaan reaksi dapat menunjukkan zat-zat pereaksi (reaktan) dan zat hasil reaksi (produk) yang terlibat selama reaksi. Dalam persamaan reaksi setara dapat terlihat adanya koefisien reaksi yang menunjukkan perbandingan jumlah partikel yang yang terlibat dalam reaksi. Maka, dapat disimpulkan perbandingan jumlah partikel zat sama dengan perbandingan jumlah mol zat. Jadi,  

[tex]\boxed{\boxed{\bold{Perbandingan~Koefisien~=~Perbandingan~mol}}}[/tex]

[tex]\mathbf{2.~Pereaksi~Pembatas }[/tex]

Pereaksi pembatas adalah zat pereaksi yang habis bereaksi sedangkan pereaksi yang lainnya berlebih karena terdapat sisa.  

Cara menentukan pereaksi pembatas adalah :

1. Persamaan reaksi harus sudah setara

2. Menentukan mol masing-masing zat pereaksi

3. Membuat MRS (Mula-mula, Reaksi, Setimbang)

4. Meletakkan mol mula-mula setiap zat pereaksi

5. Membagi masing-masing mol zat pereaksi dengan koefisiennya

4. Hasil bagi paling kecil merupakan pereaksi pembatas

[tex]\mathbf{3.~Senyawa~Hidrat~(Air`Kristal) }[/tex]

Senyawa yang mengandung air kristal disebut senyawa hidrat, sedangkan senyawa yang tidak mengandung air kristal disebut senyawa anhidrat. Air kristal merupakan molekul air yang terkandung dalam susunan kristal senyawa.

Contoh :

MgSO4 x H2O             --- >        MgSO4            +         x H2O

Senyawa hidrat/  senyawa anhidrat      kristal/hidrat

senyawa kristal

Menghitung jumlah kristal/hidrat dengan cara :

a. Membuat perbandingan mol antara senyawa anhidrat dibanding kristal/hidrat nya.

b. Besar nya nilai perbandingan dari senyawa anhidrat harus “1”.

Ar C = 12

Ar H = 1


[tex]\boxed{\boxed{\bold{Ditanya}}}[/tex]

massa CO₂


[tex]\boxed{\boxed{\bold{Jawab}}}[/tex]

Menentukan persamaan reaksi setara

C₂H₂ (g) + O₂ (g) ---> CO₂ (g) + H₂O (l)           (reaksi belum setara)

2C₂H₂ (g) + 5O₂ (g) ---> 4CO₂ (g) + 2H₂O (l)           (reaksi setara)

Menentukan Mr C₂H₂

Mr C₂H₂ = 2. Ar C + 2. Ar H

Mr C₂H₂ = 2. 12 + 2. 1

Mr C₂H₂ = 24 + 2

Mr C₂H₂ = 26

Menentukan jumal mol (n) C₂H₂

n C₂H₂ = [tex]\frac{massa}{Mr}[/tex]

n C₂H₂ = [tex]\frac{25}{26}[/tex]

n C₂H₂ = 0,96 mol

Menentukan jumlah mol (n) CO₂

[tex]\boxed{\boxed{\bold{Perbandingan~Koefisien~=~Perbandingan~mol}}}[/tex]

                       2C₂H₂ (g) + 5O₂ (g) ---> 4CO₂ (g) + 2H₂O (l)

Koefisien            2         :       5        :         4         :      2

Mol                    0,96 mol

n CO₂ = 2 x n C₂H₂

n CO₂ = 2 x 0,96

n CO₂ = 1,92 mol

Menentukan Mr CO₂

Mr CO₂ = 1. Ar C + 2. Ar O

Mr CO₂ = 1. 12 + 2. 16

Mr CO₂ = 12 + 32

Mr CO₂ = 44

Menentukan massa CO₂

n CO₂ = [tex]\frac{massa}{Mr}[/tex]

massa CO₂ = n x Mr CO₂

massa CO₂ = 1,92 x 44

massa CO₂ = 84,48 gram

massa gas CO₂ yang dihasilkan adalah 84,48 gram

14. how many moles of water is 5.87 x 10 22 molecules ?


Saya jawabnya pakai bahasa indonesia ya :p

Diketahui : Jumlah partikel :  5.87 x [tex]10^{22}[/tex]

Jumlah partikel = mol x L (bilangan avogadro)

5.87 x [tex]10^{22}[/tex] = mol x 6.02 x [tex]10^{23}[/tex]

mol = 0.097 mol

17. How many moles are there in44g of CO2? How many molecus is this


simply the molar mass of co2 is 44g/mol. It is calculated as below;

molar mass of c = 12 g/mol

molar mass of o= 16 g/mol

molar mass of co2= molar mass of c+ 2(molar mass of o)= (12+16+16)g/mol=44g/mol

number of moles = the given mass / molar mass of co2

number of moles= 44 g / 44 g/mol =1 mol

therfore 44g of co2 have 1 mole of co2 in it.
