Chapter 20, Problem 37QAP

Interpretation Introduction

Interpretation:

The amount of nickel sulfide ore (NiS) should be calculated which is required to produce one metric ton of stainless steel.

Concept introduction:

The moles of any compound or element can be calculated by given formula:

$n=\frac{m}{M}$

Where, n is number of moles, m is given mass, and M is molar mass.

In ionic compounds, the moles of each ion are equal to the moles of its formula unit.

For example; 1 mole of NaCl will have 1 mole of Na+ -ion and 1 mole of Cl- -ion.

The conversion factor for metric ton to gram is as follows:

${\text{1 metric ton = 1000 kg = 10}}^{\text{6}}\text{ g}$
