Could anyone help me out ?

density = mass/volume = 100kg/10ml = 10kg/ml
voluime = mass/density = 50g/2 g/ml = 25 ml
mass = density x volume = 2x55 = 110 kg
All of these are answered by using one formula . . . the definition of Density. Density = Mass / Volume . For each problem, substitute the given numbers into that formula, and solve it for the unknown number. (Don't forget to keep the correct units all the way through each one.)
