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

Respuesta :

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
