2.
vol = jmlh mol . STP / L
vol = 9,03x10*24 . 22,4 / 6,02x10*23
vol = 15 . 22,4
vol = 336 liter

1.Jika yang dimaksud menghitung massa atom relatif X 

mol X = 7.525 x 10^22 / 6.02 x 10^23 = 1.25x10^-1 = 0.125 mol 

Ar X = 5 / 0.125 = 40 g/mol <--

2.vol = jmlh mol . STP / L
vol = 9,03x10*24 . 22,4 / 6,02x10*23
vol = 15 . 22,4
vol = 336 liter <--
