Answer 1

44g of CO2 has 12 got carbon
1 g will have -12/44g of Carbon
2g of CO2 will have (12/44)×2
-0.5g of carbon.

Answer 2

Hi,

Molecular mass of carbondioxide (CO₂) is   = 12+ (2 × 16)  

                                                                      = 44 g  

12  g of carbon is present in 44 g of Carbondioxide.

Therefore, mass of carbon present in 2 of Carbondioxide is = 12/44 × 2

                                                                                                  = 0.545 g

Hope this answers your question,
