masa moleculara:
O2
A(O) = 16
M(O2) = 2x16 = 32 g/mol
Al2S3:
A(Al) = 27, A(S) = 32
M(Al2S3) = 2x27+3x32 = 150 g/mol
Mg(OH)3
A(Mg) = 24, A(O) = 16, A(H) = 1
M(Mg(OH)3) = 24+(16+1)x3 = 75 g/mol
Al2(SO4)3
A(Al) = 27, A(S) = 32, A(O) = 16
M(Al2(SO4)3) = 2x27+(32+4x16)x3 = 150 g/mol
molul:
1 mol O2 = 32 g
1 mol Al2S3 = 150 g
1 mol Mg(OH)3 = 75 g
1 mol Al2(SO4)3 = 150 g
kilomolul
1 Kmol O2 = 32 Kg
1 Kmol Al2S3 = 150 Kg
1 Kmol Mg(OH)3 = 75 Kg
1 Kmol Al2(SO4)3 = 150 Kg
