What is the price of 1 cm³ of mercury?

$

What is the price of 1 in³ of mercury?

Answer 1

Solution:1)What is the price of one pound of mercury?

$\dfrac{158.50}{76\;lbs}=2.085$ $

2)What is the price of 1 g of mercury?

$76\; lbs\;*\;\dfrac{1000g}{2.2046\;lbs}=34473g$

$\dfrac{129}{34473g}=0.0037$ $

3)What is the price of 1 cm³ of mercury?

1 cm³ is equivalent to 13.534 g, so that:

$13.534\;g\;*\;0.0037$$ = $0.050$$

4)What is the price of 1 in³ of mercury?

1 cubic inch = 2.54³ = 16.387 cm³

$0.050$$ $*\;16.387\;cm^3=0.82$$
