Final answer:
To find the milligrams of mercury in 250.0 mL of the metal, multiply the volume by the density of mercury (13.6 g/mL) and convert grams to milligrams resulting in 3400000 mg.
Step-by-step explanation:
To determine the mass of mercury in 250.0 mL of the metal, we need to use the density of mercury, which is 13.6 g/mL. To calculate the mass, we multiply the volume of the mercury by its density:
Mass = Density × Volume
Mass = 13.6 g/mL × 250.0 mL
Mass = 3400 g
Since we want the mass in milligrams, we need to convert grams to milligrams:
1 g = 1000 mg
Mass = 3400 g × 1000 mg/g
Mass = 3400000 mg
Therefore, there are 3400000 milligrams of mercury in 250.0 mL of the metal.
