Question

Mercury is a liquid metal having a density of 13.6 g/mL. What is the volume of 1.50 lb of mercury metal? 1kg = 2.2 lbs

Hint: Convert lbs to kg to g then solve for volume.
a: 19.9 mL
b: 50.1 mL
C: 11.0 mL
D: 33.4 ml

Answer 1

The answer is option B

Step-by-step explanation:

The denisty of a substance can be found by using the formula

`Density(\rho) = (mass)/(volume)`

Making volume the subject we have

`volume = (mass)/(Density)`

From the question

Density = 13.6 g/cm³

mass = 1.50 lbs

We must first convert the lbs to grams in order to solve

That's

if 2.2 lbs = 1 kg

Then 1.50 lbs =
`(1.5)/(2.2)`

= 0.681 kg

If 1 kg = 1000 g

Then 0.68 kg = 0.681 × 1000 = 681g

So the mass = 681 g

Substitute the values into the above formula and solve for the volume

That's

`volume = (681)/(13.6)`

= 50.0735

We have the final answer as

50.1 mL

Hope this helps you
