Question

An apple has a mass of 150g and a volume of 100cm3
Find its density in g/cm3?

Answer 1

 I think you mean a volume of 100 cm3. In that case you need to divide 150:100 to find out what the density in g/cm3 is. So 150:100 = 1.5 g/cm3

Answer 2

Since density is mass over volume given Mass-150g Volume-100cm 150/100 Density -1.5g/cm3
