Question

1. calcium chloride has a density of 2.50 g/cm³. if you have 218 g of it, what volume do you have? a. 87.2 cm³ b. 545 cm³ c. 87.2 g d. 545 g

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 $m = 218\ g$ and $
ho=2.50\ g/cm^{3}$. Substituting these values into the formula $V=\frac{m}{
ho}$, we get $V=\frac{218\ g}{2.50\ g/cm^{3}}$.

Step3: Calculate the volume

$V = 87.2\ cm^{3}$.

Answer:

A. $87.2\ cm^{3}$
