Chapter 3, Problem 3.4QP

Interpretation Introduction

Interpretation:

The determination of composition of $\text{C, H and O}$ in given compound should be explained.

Concept introduction:

Mole:

Number of atoms present in gram atomic mass of element is known as Avogadro number.

Avogadro number is $6.022136\times {10}^{23}$

One mole equal of atom equal to Avogadro number $(6.022136\times {10}^{23})$ hence, 1 mole of Iron contain atom $6.022136\times {10}^{23}$ $\text{Fe}$ atoms.

The mole of taken gram mass of compound is given by ration between taken mass of compound and molar mass of compound.

$\text{Mole}\text{=}\frac{\text{Mass}}{\text{Molar}\text{mass}}$

Mass percent:

The mass percent of analyte, which is present in taken amount (mass) of sample, is given by percent ratio of mass of analyte and taken mass of sample.

$\text{Mass}\text{present}\text{=}\frac{\text{Mass}\text{of}\text{analyte}}{\text{Mass}\text{of}\text{sample}}\times 100$
