Tentukan jumlah mol senyawa NaCl 106 gram jika diketahui Ar Na = 23 dan Ar Cl = 35
mol = massa / Mr = 106/58 =1,8 mol
mol= massa / Mr = 80 / 40 = 2 mol
mol= massa / Mr = 106/23=4,6 mol
mol= massa / Mr = 106/35 = 3,0 mol

Tentukan massa dari 0,1 mol CO(NH2)2 , jika diketahui Ar C = 12 , Ar O =16 , dan Ar N = 14 dan Ar H = 1
massa = mol × Ar atau Mr = 0,1 × 14 = 1,4 gram
massa = mol × Ar atau Mr = 0,1 × 60 = 0,6 gram
massa = mol × Ar atau Mr = 0,1 × 60 = 6 gram
massa = mol × Ar atau Mr = 0,1 × 14 = 14 gram
