Massa larutan =massa jenis x volume
Massa larutan = 500ml x 1,2 gr/ml =600 gram
massa H2SO4 = 5M x 600 gram =30 gram
massa pelarut = 600-30 gram =570 gram
 
molalitas(m) =grm : Mr x 1000 : masa jenis = 30:98 x 1000:570 =0,54 molal
terimakasih..
tapi itu massa H2SO4 = 5M x 600 gram =30 gram ? bukannya 300?
5M mksutnya 5 : 100 % x 600 gr
