Question

q19. a piece of metal with a mass of 150 g has the volume of 60 ml. what is density of the metal?
7 gram/ml
6 gram/ml
0.17 gram/ml
0.5 gram/ml
3.3 grams/ml
2.5 grams/ml
0.04 grams /ml

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 $V=60$ mL. So $
ho=\frac{150}{60}$.

Step3: Calculate density

$\frac{150}{60}=2.5$ g/mL.

Answer:

2.5 grams/mL
