Calculate the mass of 0.72 molecules of CO2

1.	Calculate the mass of 0.72 molecules of CO2
Answer» Molecular mass of CO2 = Atomic mass of C + 2 {tex}\\times{/tex}\xa0Atomic mass of O= (12u + 2 {tex}\\times{/tex}\xa016u) = 44uGram molecular mass of CO2 = 44 g1 gram molecule of CO2 = 44 g0.72 gram molecule of CO2 {tex} = \\frac{{\\left( {44g} \\right)}}{{\\left( {1g} \\right)}} \\times \\left( {0.72g} \\right) = 31.68g{/tex}
