Chapter 3, Problem 89IAE

Interpretation Introduction

Interpretation:

Whether the weight of ${\text{S}}_{\text{8}}$ sample $\text{1}\text{.00}\times {\text{10}}^{-23}\text{ g}$ is possible or not should be determined along with the smallest possible mass of ${\text{S}}_{\text{8}}$. The answer should be expressed in appropriate SI units so that its value will be greater than 1.

Concept introduction:

Molar mass of the molecule is equal to the sum of the masses of atoms present in the molecule.

Mole is SI unit which is used to measure the quantity of the substance. It is the quantity of a substance which contains the same number of atoms as present in accurately 12.00 g of carbon-12 is known as mole.

The one mole of any substance is equal to the Avogadro number i.e. $6.022\times {10}^{23}$ atoms.

Number of moles of compound can be calculated by below formula:

Number of moles = $\frac{\text{given mass of the compound}}{\text{molar mass of the compound}}$

A conversion factor is a numerical ratio which is used to show a measurement in one unit as another unit. It is always equal to 1.
