Question

1. at standard temperature and pressure, krypton has a density of 0.003749 g/ml. a sample of krypton has a mass of 3.09 g. what is the volume of the krypton?

Explanation:

Step1: Recall density formula

The density formula is $
ho=\frac{m}{V}$, where $
ho$ is density, $m$ is mass and $V$ is volume. We need to solve for $V$, so we can re - arrange the formula to $V = \frac{m}{
ho}$.

Step2: Substitute given values

We are given that $m = 3.09$ g and $
ho=0.003749$ g/mL. Substituting these values into the formula $V=\frac{m}{
ho}$, we get $V=\frac{3.09}{0.003749}$ mL.

Step3: Calculate the volume

$V=\frac{3.09}{0.003749}\approx824.22$ mL

Answer:

824.22 mL
