Question

A 76.00 pound flask of mercury costs $156.50. The density of mercury is 13.534 g/cm3.
Find the price of one cubic inch of mercury by calculating intermediate values.

What is the price of one pound of mercury?

Answer 1

To find the unit price just divide the total cost by the amount of that item

\(\large \frac{total~cost}{amt~of~pounds}\rightarrow \frac{156.50}{76}\)

Answer 2

it's also asking for the price of one cubic inch which is a little more complicated

you'd first convert lbs to grams (1 lb = 453.592g), then g to cm^3 using density (13.534 g/cm3. ) then divide (total cost paid)/(total cubic inches)
