Chapter 16, Problem 16.14P

Interpretation Introduction

Interpretation:

Given reaction has to be balanced and the molarity of molybdate present in the unknown has to be calculated.

Concept introduction:

• There is a law for conversion of mass in a chemical reaction i.e., the mass of total amount of the product should be equal to the total mass of the reactants.
• The concept of writing a balanced chemical reaction is depends on conversion of reactants into products.
• First write the reaction from the given information.
• Then count the number of atoms of each element in reactants as well as products.
• Finally obtained values could place it as coefficients of reactants as well as products.

Molarity (M):

Molarity is one of the concentration unit. Molarity is defined as number of moles of the solute in one litre of solution.

$\text{Molarity =}\frac{\text{Number of moles of the solute}}{\text{1L solution}}$
