Question

18 a substance has a volume of 150 ml and a mass of 300 g. calculate its density. a 1.5 g/ml b 2.5 g/ml c 2.0 g/ml d 2.0 g/ml

Explanation:

Step1: Recall density formula

Density ($
ho$) is given by $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

We have $m = 300\ g$ and $V=150\ mL$. So, $
ho=\frac{300\ g}{150\ mL}$.

Step3: Calculate density

$
ho = 2.0\ g/mL$.

Answer:

C. 2.0 g/mL
