Question

Number of atom in4.4g of CO2?​

Answer 1

Answer:

Explanation:

Molar mass CO2 = 44 g/mol  

You have 4.4g , so you have 4.4/44 = 0.1 mol CO2  

1mol CO2 has 6.022*10^23 molecules  

0.1mol CO2 has (6.022*10^23)*0.1 = 6.022*10^22 molecules  

1molecule of CO2 contains 2 atoms of O  

Therefore, 6.022*10^22 molecules of CO2 will contain (6.022*10^22) *2 = 1.204*10^23 atoms O

Answer 2

Answer:18.066×10*22

Explanation:

n=Given Mass/ molecular mass

n=4.4/ 44=0.1

No. Of atoms = n× Avogadro no.× no. of atoms = 0.1×6.022×10*23× 3=18.066×10*22
