Chapter 1, Problem 120QRT

Interpretation Introduction

Interpretation:

When $\text{50}\text{.0}\text{mL}$ of ethanol with density $\text{0}\text{.789}\text{g/mL}$ is mixed with $\text{50}\text{.0}\text{mL}$ of water with a density of $\text{0}\text{.998}\text{g/mL}$, the resulting volume is $\text{95}\text{.6}\text{mL}$.  The density of this solution has to be calculated.

Concept Introduction:

Density:

The ratio of mass of a sample to its volume is said to be the density.

  $\text{Density = }\frac{\text{mass}}{\text{volume}}$
