Chapter 3.4, Problem 3.2CC

(a)

Interpretation Introduction

Interpretation:

The trapping of ${\text{H}}_{\text{2}}\text{O}\text{and}{\text{CO}}_{\text{2}}$ by using $\text{CuO}$ pellets should be explained and difference in resulted and actual values should be explained.

Concept introduction:

Mass percent:

The mass percent of analyte, which is present in taken amount (mass) of sample, is given by percent ratio of mass of analyte and taken mass of sample.

$\text{Mass}\text{present}\text{=}\frac{\text{Mass}\text{of}\text{analyte}}{\text{Mass}\text{of}\text{sample}}\times 100$
