How many grams of nitric acid can be prepared from the reaction of 138 grams of NO2 with 54 grams of H2O according to the equation: 3NO2 + H2O -> 2HNO3 + NO

Insoluble salts are made by precipitation. An equation for the preparation of barium
sulfate is given below.
BaCl 2
(aq) + MgSO4

(aq) o BaSO4

(s) + MgCl 2
(aq)

This reaction can be used to fi nd x in the formula for hydrated magnesium sulfate

O.

A known mass of hydrated magnesium sulfate, MgSO4
.xH2
O, was dissolved in water.
Excess aqueous barium chloride was added. The precipitate of barium sulfate was
fi ltered, washed and dried. Finally it was weighed.
Mass of hydrated magnesium sulfate = 1.476 g
Mass of barium sulfate formed = 1.398 g
The mass of one mole of BaSO4
= 233 g
The number of moles of BaSO4

formed = ............... [1]
