Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Please see below solution:

1 lb Hg x (151.50/76 lb) = cost of 1 lb. 
<span>cost 1 lb x (1g/453.6 g) = cost of 1 g.</span>

Answer:

cost of 1 cm^{3} mercury is \$ 0.059477

cost of 1 in^{3} mercury is \$ 0.97466

cost of 1 pound mercury is \$ 1.99

cost of 1 g mercury is \$ 0.00439

Explanation:

We know, density = \frac{mass}{volume}

1 pound =453.6 g

So, mass of 76.00 pound mercury = (76.00\times 453.6)g=34473.6g

So, volume of 34473.6 g mercury = \frac{34473.6g}{13.534g/cm^{3}}= 2547.2 cm^{3}

So, cost of 2547.2 cm^{3} mercury is \$ 151.50

Hence cost of 1 cm^{3} mercury is \frac{\$ 151.50}{2547.2}=\$ 0.059477

1 cm^{3} = 0.061024 in^{3}

So, cost of 0.061024 in^{3} mercury is \$ 0.059477

Hence, cost of 1 in^{3} mercury is \frac{\$ 0.059477}{0.061024}=\$ 0.97466

Cost of 76.00 pound mercury is \$ 151.50

So, cost of 1 pound mercury is \frac{\$ 151.50}{76.00}=\$ 1.99

Cost of 34473.6 g of mercury is  \$ 151.50

So, cost of 1 g mercury is \frac{\$ 151.50}{34473.6}=\$ 0.00439
