The density of mercury is 13.5g/mL. What is the volume of this liquid if the sample weighs 12.5 pounds?

Mama L [17]

Answer : The volume of liquid is 420 mL.

Explanation :

Density : The mass per unit volume of a substance is known as density.

Formula used:

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

As we are given:

Density of mercury = 13.5 g/mL

Mass = 12.5 pounds

First we have to convert mass of sample from pound to gram.

Conversion used:

As, 1 pound = 453.6 g

So, 12.5 pounds = 453.6 × 12.5 g = 5670 g

Now we have to calculate the volume of liquid.

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Now putting all the given values in this formula, we get:

$13.5g/mL=\frac{5670g}{\text{Volume}}$

Volume = 420 mL

Therefore, the volume of liquid is 420 mL.
