Question

Calculate tje mass of carbon present in 2g of Co2
​

Answer 1

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,
