What is the density of a book whose mass is 1,800 g and whose volume is 300 cm3?

*My Answer*You want to identify the numbers first, density = mass ÷ volume. Which would give you, 1800g ÷ 300 cm³ = 6 g/cm³.

*Cant Figure Out *What is the mass of a ball whose density is 0.250 g/cm3 and whose volume is 200 cm3

• Science -

6.00 g/cc is right.
mass = v x d
mass = 200 cc x 0.250 g/cc = ?
