When natural gas burns, CO2 is formed. If 0.25 moles of CO2 is formed, what mass of CO2 is produced? 
Difficulty: Easy

Problem solving strategy:

Carbon dioxide is a molecular substance. Determine its molar mass and use it to convert moles to mass in grams.

0.25 moles of CO2 ➝ ?g of CO2

 

Solution:

Molar mass of CO2

= 12 + (16 x 2)

= 44 g

1 mole of CO2 = 44 g of CO2

 

So, 0.25 moles of CO2

= 44 x 0.25

= 11g of CO2
