Best Answer
  • One time the Atomic Mass of carbon (12 g/mol C) = 12
  • Two times the atomic mass of oxygen (16 g/mol O) = 32
  • Adding up both (totalizing 1*12 and 2*16) gives the molar mass of CO2 = 44 g/mol CO2

Carbon Atomic Weight - 12.011

Oxygen Atomic Weight - 15.994

CO2 Formula Weight = 12.011 + (15.994 x 2) = 43.999

carbonic acid is H2CO3.

so formula mass is= (2*1)+12+(3*16)

=62g
