Three questions: Must show work how you got it. I am really confused on how to solve these:

1) The element, barium, has a density of 3.50 g/mL. What would be the mass of a rectangular block of barium with the dimensions, 1.00cm x 3.0 x 5.00 cm?

2) A small metal sphere has a mass of 75.0 g. It is placed in a graduated cylinder containing water. The water level in the cylinder changes from 10.0 mL to 20.0 Ml when the sphere is put into water. What is the density of the sphere?

3) Which of the following contains the greatest mass of mercury? must convert all to same unit. (Density of mercury= 13.6 g/mL) 

a: 0.600 L

b. 0.600 kg

c. 0.600 lb
