What mass of sodium chloride would be decomposed by 9.8 g of sulphuric acid. If 12 g of sodium bisulphate and 2.75 g of hydrogen chloride were produced in a reaction assuming aht the law of conservation of mass is true?

Answer»

Solution :`NACL+H_(2)SO_(4)=NaHSO_(4)+HCl`
ACCORDING to law of conservation of mass.
TOTAL masses of reactants =Total masses of products
Let the mass of NaCl decomposed be xg, so
`x+9.8=12.0+2.75=14.75
x=4.95g
