Calculate the number of CO2 molecules in 0.0334 molmol of CO2.

Express your answer using three significant figures.

2.01*10²² molecules are in 0.0334 moles of CO₂

Explanation:

The relation we must to know, is that one mol is occupied by 6.02*10²³ molecules.

In order to calculate the number of dioxide molecules we can do this conversion → from moles to number of molecules

0.0334 mol. 6.02*10²³ molecules / 1 mol = 2.01*10²² molecules

We can also propose a rule of three:

1 mol contains 6.02*10²³ molecules

0.0334 moles will be contained by (0.0334. 6.02*10²³) / 1 = 2.01*10²²
