How many molecules of CO2 are the in 4.56 moles of CO2 ?
1. How many molecules of CO2 are the in 4.56 moles of CO2 ?
° STOIKIOMETRI °
Given
n = 4,56 moleL = 6,02 • 10²³Ask
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 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
Semoga membantu :D
4. For the 250 ml, 0.2 M sodium chlorine solution, calculate the masa of sodium chlorine. Mass of sodium chlorine ... Gram ?
mol NaCl = 250 ml x 0.2 M
= 0.25 L x 0.2 M
= 0.05 mol
maka massa NaCl = 0.05 mol x Mr NaCl
= 0.05 x 58, 5
= 2.925 gram
5. How many grams are in 1.2 x 10²⁴ molecules of water?
Answer
Mass of water = 36 grams
ExplanationMolecules 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

6. Apa itu Chlorine????????????
Chlorin adalah unsur hologen yang banyak di temukan dialam namun jarang di temukan dalam bentuk bebasChlorine (kaporit) adalah bahan kimia yang paling sering digunakan membunuh bakteri yang cukup sederhana pada kolam renang, namun mengandung reaksi kimia. chlor yang anda tuangkan ke dalam air kolam, terinci ke dalam berbagai bahan kimia, termasuk asam hypochlorous (HOCl) dan hypochlorite ion (Ocl) Kedua unsur tersebut
7. How many moles of sodium bromide can be formed from 1.55 moles of aluminum bromide?

8. 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.
9. ______ reacts with a chlorine atom, an electron is transferred from the outer shell of the sodium atom to the outer shell of the chlorine atom
Jawaban:
When a sodium atom
Penjelasan:
Ketika atom natrium bereaksi dengan atom klor, elektron ditransfer dari kulit terluar atom natrium ke kulit terluar atom klor
10. Chlorine+helium= Hydrogen+oxygen=
1. Klor + Helium tidak bisa bereaksi, karena Helium sudah stabil dengan elektron valensi 2.
2. [tex] H + \frac{1}{2}O_2 => H_2O[/tex]
Hidrogen + Oksigen => Dihidrogen Monoksida (Air).
Tolong kalau bisa pertanyaannya diperjelas
11. jenis penyusunan chlorine
Penjelasan:
Klorin adalah unsur kimia dengan simbol Cl dan nomor atom 17. Senyawa ini adalah halogen kedua paling ringan, berada diantara fluor dan bromin dalam tabel periodik dan sifat-sifatnya sebagian besar di antara mereka. Klorin berwujud gas berwarna kuning-hijau pada suhu kamar. Unsur ini merupakan elemen sangat reaktif dan oksidator kuat: klorin mempunyai afinitas elektron tertinggi dan elektronegativitas ketiga tertinggi di belakang oksigen dan fluor.
