Question

the number of oxygen atom in 4.4g of CO2 in approximately will be?

Answer 1

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

Answer 2

hope this helps you☺️
