What is the molarity of sodium sulphate in a solution prepared by dissolving 15.5g in enough water to make 35ml of solution?

Molarity = moles of solute/volume of solution
Find moles NaCl
55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl
Molarity = 0.941 moles NaCl/35 Liters
= 0.027 Molarity NaCl
( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )

15.5 grams Na2SO4 (1 mole Na2SO4/142.05 grams) = 0.1091 moles Na2SO4
Now,
Molarity = moles of solute/ Liters of solution ( 35 ml = 0.035 Liters )
Molarity = 0.1091 moles Na2SO4/0.035 Liters
= 3.1 M Na2SO4 solution

What happens when freshly prepared solution of ferrous sulphate followed by conc.H2SO4 is added to nitric acid?
You can obtain the ferric sulphate - Fe2(SO4)3; because the ferrous sulphate react as a reducing agent.
Is it advisable to store ferrous sulphate in a zinc container?
No. The zinc will react with the ferrous sulphate, dissolving the zinc and forming solid iron. This is due to the positions of iron and zinc in the activity series.See the Related Questions for more information about the activity series.
