Chapter 1.10, Problem 1.29P

Interpretation Introduction

Interpretation:

The mass (in grams) of diethyl ether, whose volume is $\text{10}\text{.0}\text{mL}$ and density is $\text{0}\text{.713}\text{g/mL}$ has to be calculated.

Concept Introduction:

Density:  Density is the relationship between the mass of a substance to its volume.  Density is represented in grams per milliliter $\left(\text{g/mL}\right)$ or grams per cubic centimeter $\left(\text{g/cc}\right)\text{.}$  The formula is,

  $\text{Density=}\frac{\text{Mass}\left(\text{g}\right)}{\text{Volume}\left(\text{mL}\text{or}\text{cc}\right)}$

Mass of a substance can be calculated as,

  $\underset{\text{Volume}}{\underbrace{\cancel{\text{mL}}}}\text{×}\underset{\text{Density}\text{of}\text{a}\text{substance}}{\underbrace{\frac{\text{g}}{\cancel{\text{mL}}}}}$

Milliliters cancel each other and mass of a substance can be found.
