The molar mass of co2 is 44.01 g/mole. choose which of the following correctly represents this relationship correctly as a conversion factor. 1 mol co2 = 44.01 g co2 44.01 mol co2 = 1 g co2 44.01 molecules co2 = 1 g co2 1 molecule co2 = 44.01 g co2

By definition, one mole of any substance is equal to its molecular mass expressed in grams.

The molecular mass of CO2 is = M(C) + 2*M(O)

                                                   = 12 + 2(16) = 12 + 32 = 44 grams

Therefore: 1 mole of CO2 = 44 g of CO2

Ans: (a)
