Chapter 11, Problem 11.146QP

Interpretation Introduction

Interpretation: The percent of Zn in the alloy has to be calculated.

Concept Introduction:

Ideal gas is the most usually used form of the ideal gas equation, which describes the relationship among the four variables P, V, n, and T.  An ideal gas is a hypothetical sample of gas whose pressure-volume-temperature behavior is predicted accurately by the ideal gas equation.

$\text{PV = nRT}$

The molar mass formula

$\text{M}\text{=}\frac{\text{mass}\text{(in}\text{g)}}{\text{mol}}$

The mass percent of Zn

$\text{mass\%}\text{Zn}\text{=}\frac{\text{mass}\text{Zn}}{\text{mass}\text{sample}}\text{×}\text{100\%}$
