Given that the molar mass of carbon is 12 g/mol and the molar mass of oxygen is 16 g/mol, calculate the molar mass of carbon dioxide, co2.

Molar mass of oxygen is:
M(O)=16 g/mol
Molar mass of carbon is:
M(C)=12 g/mol  
Molar mass of carbon dioxide is:
M(CO2)=M(C)+2*M(O)
 M(CO2)=12 g/mol+2*16g/mol
M(CO2)=44 g/mol

Molar mass(M) is the mass of 1 mole of the substance (grams per mole of a compound).

False, as a substance changes from a solid to a liquid and from a liquid to a gas the molecules get farther apart from each other
