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

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
