Answer:
50.3mL of mercury are in 1.50lb
Step-by-step explanation:
Punds are an unit of mass. To convert mass to volume we must use density (13.546g/mL). Now, As you can see, density is in grams but the mass of mercury is in pounds. That means we need first, to convert pounds to grams to use density and obtain volume of mercury.
Mass mercury in grams:
1.50lb * (1kg / 2.20lb) = 0.682kg = 682g of mercury.
Volume of mercury:
682g Mercury * (1mL / 13.546g) =
50.3mL of mercury are in 1.50lb
