Question

Calculate the molecular masses of H2, O2, CO2, CH4, C2H6, C2H4, CI2, NH3, CH3OH, HNO3

Answer 1

Molecular mass of H2 = 2(1) =2 g
Molecular mass of o2 = 2(16) =32g
Molecular mass of co2= 12 +2(16)=12+32=44g
Molecular mass of ch4=12+4(1)=12+4=16g
Molecular mass of C2h6=2(12)+6(1)=24+6=30g
Molecular mass of c2h4=2(12)+4(1)=24+4=28g
Molecular mass of cl2= 2(35.5)=71g
Molecular mass of NH3= 14+3(1)=14+3=17g
Molecular mass of ch3oh= 12+3(1)+16+1= 32g
Molecular mass of hno3= 1+ 14+3(16)=63g
