Molecular weight of aluminium is 27g/mol
So 2.5 mol is 2.5 x 27 = 67.5 g
0.015 mol of Calcium is 0.6 g
1.25 x 10-3 mol of Iron = 0.0697 g
653 mol of neon = 13177 g
62) a) gold 835.3 g
b) He 62.4 g
c) Platinum = 12.28 g
d) Pu = 0.0886 g
63) a) Cu Mw = 63.5 g/mol
So 127.08 g/63.5 = 2 mol
b) Lithium = 1.73 x 10-3 mol
c) Americium = 2.06 x 10-5 mol
d) Aluminium = 0.25 mol
64) a) Na = 0.695 mol
b) Tin = 7.38 x 10-3 mol
c) platinum = 1.74 x 10-5 mol
d) Xe = 7.49 x 10-3 mol
