# What is the density of a 0.196*g mass of gas, confined to a 100*mL volume?

Sep 15, 2017

$.00196 \frac{g}{m l}$

#### Explanation:

Density is mass over volume. (Mass per unit volume).

So...

$\frac{0.196 g}{100 m l} \mathmr{and} .00196 \frac{g}{m l}$

Well, $\rho = \text{Mass"/"Volume}$

#### Explanation:

And so we simply work out the quotient.....

$\rho = \frac{0.196 \cdot g}{100 \cdot m L} = 1.96 \times {10}^{-} 3 \cdot g \cdot m {L}^{-} 1$.....
