Penjelasan:
1. mol = gr/Mr = 34/17 = 2 mol
vol stp = 22,4 x mol = 2 x 22,4 = 44,8
jml atom = 6,022 x 10^23 x mol = 2 x 6,022 x 10^23 = 12,044 x 10^23
2. massa = mol x Mr = 0,1 x 18 = 1,8 gram
vol stp = 22,4 x 0,1 = 2,24
jml atom = 6,022 x 10^23 x 0,1 = 6,022 x10^22
3. mol = vol stp / 22,4 = 5,6 x 22,4 = 0,25 mol
massa = 0,25 x 44 = 11
jml atom = 0,25 x 6,022 x 10^23 = 1,5055 x 10^23
4. mol = jml atom / 6.022 x 10^23 = 6.02 x 10^22/ 6.02 x 10^23 = 0,1 mol
massa = 0,1 x 32 = 3,2 gram
vol stp = 22,4 x 0,1 = 2,24
