Question

in the reaction between copper sulphate and sodium sulphide solution when 15.9g copper sulphate completely reacts with 7.8g of sodium sulphide it is observed that 9.5g of copper sulphide is formed. what is mass of sodium sulphate solution formed

Answer 1

according to law of conversion of mass :
=>Mass of reactants =mass of products
=>Mass of copper sulphate +mass of sodium sulphide =mass of copper sulphide +mass of sodium sulphate
=>15.9+7.8=9.5+mass of sodium sulphate
=>23.7-9.5=mass of sodium sulphate
=>14.2=mass of sodium sulphate.

mass of sodium sulphate =14.2g

Answer 2

Answer:

14.2g

Explanation:

15.9+7.8=9.5+x

23.7=9.5+x

x=23.7-9.5

=14.2g
