Mercury is the only metal which is a liquid at room temperature. The density of mercury is 13.6 g/cm3. What is the mass, in pounds, of 1.00 quart of mercury? [1 liter = 1.057 quart; 1 pound = 453.6 grams]

Answer 1

To solve this problem, we need to convert the given density of mercury into mass per quart.

First, we need to convert 1 liter to quarts. Since 1 liter = 1.057 quarts, 1 quart is equivalent to 1/1.057 = 0.946 liters.

Next, we need to find the mass of 0.946 liters of mercury.

The density of mercury is given as 13.6 g/cm^3. This means that 1 cm^3 of mercury has a mass of 13.6 grams.

Since 1 liter is equivalent to 1000 cm^3, the mass of 1 liter of mercury is 13.6 grams/cm^3 * 1000 cm^3 = 13600 grams.

Now, we can convert the mass of 0.946 liters of mercury into pounds.

Using the conversion factor 1 pound = 453.6 grams, the mass in pounds is 13600 grams / 453.6 grams/pound = 29.9 pounds.

Therefore, the mass of 1.00 quart of mercury is 29.9 pounds.
