Question

a block has a mass of 150 g and a volume of 50 cm³. what is its density? 7.5 g/cm³ 0.33 g/cm³ 3 g/cm³ 2 g/cm³ 31/40

Explanation:

Step1: Recall density formula

The formula for density $
ho$ is $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 150\ g$ and $V=50\ cm^{3}$, we substitute into the formula: $
ho=\frac{150\ g}{50\ cm^{3}}$.

Step3: Calculate density

$\frac{150}{50}=3\ g/cm^{3}$.

Answer:

$3\ g/cm^{3}$
