Question

plzzzzzzzzz if u dont mine anyone can solve this. up to 5th question

Answer 1

5.a) KCl.MgCl2.6H2O
b)MgSO4.7H2O
c)CuSO4.5H2O
d)FeSO4.7H2O
e)CaSO4.2H2O
f)CaSO4.1/2H2O
g)ZnSO4.7H2O
h)Na2S2O3.5H2O
I)Na2SO4.10H2O
j)K2SO4.Al2(SO4)3.24 H2O
It is very big process to calculate the mass of these formulas.Simply search it on Google
b) Mg = 24
S = 32
O = 16
H=1
Mg + S+4×O × 7×H +2×O
= 24+32+64 × 7+32
= 120 × 39 = 4680 g
