Chapter 3, Problem 159AP

Interpretation Introduction

Interpretation:

TheAvogadro’s number is to be calculated on the basis of the given data.

Concept Introduction:

The atomic mass of elements is measured in terms of the atomic mass unit. One atomic mass unit is defined as the number of elementary particles present in $12.0\text{g}$ of carbon atom.

The number of moles isgiven by the expression, which is as follows:

$n=\frac{\text{given mass}\left(m\right)}{\text{molar mass}\left(M\right)}$

One mole of a substance contains Avogadro number of particles, that is, $6.022\times {10}^{23}$ particles.

The surface area of a circle is calculated by the expression, which is as follows:

$\text{S}\text{.A}.=\pi r^2$
