A 2.9 g sample of a pure compound contains 0.050 mol of
the compound. Use this data to calculate the molar mass of
the compound.
m — mass of compound = 2.9 g
n — amount of compount = 0.05 mol
M — molar mass of compound = ? (g/mol)
M=mn=2.9 g0.05 mol=58 g/molM= \cfrac {m}{n}= \cfrac {2.9 ~g}{0.05~~mol} = 58~g/molM=nm=0.05 mol2.9 g=58 g/mol
Answer: 58 g/mol
