Chapter 21, Problem 21.54QP

Interpretation Introduction

Interpretation:

The molar mass of the metal from the given mass of metal oxide has to be calculated.

Concept introduction:

Molar mass: The mass of one mole of substance in grams is known as molar mass.  The formula to calculate molar mass is as follows

$\text{Molar}\text{mass}\text{=}\frac{\text{mass}\text{of}\text{substance in grams}}{\text{mole}}$

Normally an element’s molar mass in grams is numerically equal to atomic mass in atomic mass units of that element.
