a) NaOH
Na = 1 x 23 = 23
O = 1 x 16 = 16
H = 1 x 1 = 1
23 + 16 + 1 = 50g/mol
b) CO²
C = 1 x 12 = 12
O = 2 x 16 = 32
32 + 12 = 44g/mol
c)H³PO⁴
H = 3 x 1 = 3
P = 1 x 31 = 31
O = 4 x 16 = 64
3 + 31 + 64 = 98
d)C⁴H¹⁰
C = 4 x 12 = 48
H = 10 x 1 = 10
48 + 10 = 58g/mol
e) MgSO⁴
Mg = 1 x 24 = 24
S = 1 x 32 = 32
O = 4 x 16 = 64
24 + 32 + 64 = 120g/mol
