First, convert 1 quart of mercury to liters: 1 quart = 1/1.057 liters ≈ 0.946 liters. The density of mercury is 13.6 g/cm³, and there are 1000 cm³ in a liter, so the mass of mercury in 0.946 liters is 0.946 liters * 13.6 g/cm³ * 1000 cm³/liter = 12865.6 grams. To convert grams to pounds, use the conversion factor 1 pound = 453.6 grams: 12865.6 grams / 453.6 grams/pound ≈ 28.4 pounds.
