Answer to Question #350556 in General Chemistry for kay

Question

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.

Answer 1

m — mass of compound = 2.9 g

n — amount of compount = 0.05 mol

M — molar mass of compound = ? (g/mol)

$M= \cfrac {m}{n}= \cfrac {2.9 ~g}{0.05~~mol} = 58~g/mol$

Answer: 58 g/mol
