Question

In a reaction 4.3g of sodium carbonate is reacted with 5g of ethamoic acid. The Products were 2.2g of carbon dioxide, o.9g of water and some sodium ethamoic. what is a weight of sodium ethamoic.​

Answer 1

Explanation:

According to law of conservation of mass

Mass on reactant's side = Mass of product's side

let the mass of sodium ethamoic be x

4.3 + 5 = 2.2 + 0.9 + x

9.3 = 3.1 + x

9.3 - 3.1 = x

6.2 g = x
