Question

calculate the molar mass of C2H4,CO2 (atomic mass of C=12u,O=16u)​

Answer 1

Molar mass of C2H4 is

12×2+1×4

24+4

= 28

molar mass of C2H4 is 28u.

and molar mass of CO2 is

6+16×2

6+32

38

molar mass of CO2 is 38u.

here is your answer

Answer 2

here is ur answer

C2H4= 12×2+1×4

= 28u

Co2= 6+16×2
