formula of zinc oxide in this problem should be calculated Concept Introduction: Empirical formula is a formula that shows the lowest whole number ratio of atoms or ions in a compound. The empirical formula is determined using following 4 steps, To calculate the empirical formula, mass of each element should be calculated first. If percentage by mass is given, assume the total mass of compound be 100 g. The number of moles should be calculated from mass and molar mass using the following relation: n = m M Here, m is mass and M is molar mass. The smallest mole value should be divided with all calculated moles values to obtain the ratio. The obtained ratio should be round to nearest whole number.

Chapter 8, Problem 63QAP
Interpretation Introduction

Interpretation:

formula of zinc oxide in this problem should be calculated

Concept Introduction:

Empirical formula is a formula that shows the lowest whole number ratio of atoms or ions in a compound. The empirical formula is determined using following 4 steps,

To calculate the empirical formula, mass of each element should be calculated first. If percentage by mass is given, assume the total mass of compound be 100 g.

The number of moles should be calculated from mass and molar mass using the following relation:

n=mM

Here, m is mass and M is molar mass. The smallest mole value should be divided with all calculated moles values to obtain the ratio. The obtained ratio should be round to nearest whole number.
