Question

How many oxygen atoms are present in 4.4 gram of Co2 ?

Answer 1

Molar mass CO2 = 44 g/mol

Now, you have 4.4g, which means that, 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
