Chapter 10, Problem 10.26P
Interpretation Introduction

Interpretation:

Molarity of HNO3 when 0.2619 g of Na2B4O7 requires to  21.61 mL HNO3 for titration has to be calculated.

Concept Introduction:

Molarity is quantitatively defined as moles of solute in one liter of solution. For example, 0.070 M AlCl3 indicates that in 1 L the moles of AlCl3 is 0.070 mol.

Formula to calculate molar mass from number of moles is given as follows:

  Number of moles=Given massMolar mass

Formula to calculate molarity is as follows:

  M=nV

Here,

V denotes volume.

M denotes molarity.

n denotes moles.
