Question

A block of aluminum occupies a volume of 15.0 mL and weight 40.5 g. What's the density

Answer 1

density =
`(mass)/(volume)`

=
`(40.5)/(15.0)`

= 2.7
= 2.7g/ml (grams per millilitre)

Answer 2

You are given the mass of aluminum block which is 40.5 grams and its volume at 15 milliliters. You are required to find the density of the aluminum block in grams per milliliters. You need to know that density is equal to mass over volume. Let us denote D as our density, V our volume and M as our mass. So,

D = M/V
D = (40.5 grams) / (15 milliliters)
D = 27/10 or 2.7 grams per milliliters or 2.7g/mL
