Question

calculate of percentage of composition of the constituents of CO2 ( C ,=12O=16​

Answer 1

Answer:

hey mate ur answer is .....27.27 % &  72.72 %

Explanation:

molecular mass = C + O₂

                  = 12 + 16*2

                   = 12 + 32

                   = 44 g

percentage composition of carbon  = mass of element/molecular mass * 100

                                                            =12/44 * 100

                                                             = 27.27 %

percentage composition of O₂ = 32/44 * 100

                                                    =  72.72 %
