Question

Calculate the molar mass of H2, Cl2, O2, CO2, CH4, NH3 and P4​

Answer 1

molar mass of H2=2(1)=2

molar mass of Cl2=2(35.5)=71

molar mass of O2=2(16)=32

molar mass of CO2=12+2(16)=12+32=44

molar mass of CH4=12+4(1)=12+4=16

molar mass of NH3=14+3(1)=14+3=17

molar mass of P4=4(31)=124
