Answer:

a) 1805.55$

b) 2.14$

c)0.005$

d)0.064$

e)1805.55$

Step-by-step explanation:

Density of mercury is 844.9 lb/ft3.

a) 76 pound flask of mercury is 76/844.9=0.09 ft^3. 0.09 ft^3 mercury cost 162.5$, then 1 ft^3 mercury is

[tex]p=(162.5/0.09)=1805.55[/tex]

1805.55$

b) One pound of mercury is 2.14$

[tex]p=162.5/76=2.14[/tex]

c)76 pound equals 34473 grams. It makes:

[tex]p=162.5/34473=0.005[/tex]

0.005$ is the price of one gram mercury.

d)Total amount of mercury is 34473 grams. Then total volume of mercury is:

[tex]V=34473/13.534=2547.14[/tex]

2547.14 cm3. And the unit price is:

[tex]p=162.5/2547.14=0.064[/tex]

e) 1805.55$. It is found already.
