Question

If 6.00 g of carbon is burned completely, what volume of carbon dioxide gas is released at STP?

Answer 1

The balanced chemical reaction for the combustion of carbon is,

                               C + O2 ---> CO2

Given that  

Amount of C= 6.00 g  

Number of mole = amount in g/ molar mass

= 6.00 g/ 12.01 g/ mole

= 0.5 mole

And Condition = STP  

According to balance recation 0.5 mole C will give 0.5 mole CO2 and at STP the volume  will be  

0.5 * 22.L/1. Mole = 11.2 L
