Question

a block of unknown material has a mass of 882.2 g. it measures 5.29 cm x 4.45 cm x 3.34 cm. what is the density of the block? give answer in units of g/cm3 and remember correct significant figures.

Answer 1

The density of a material can be found by using the formula:

Density = Mass / Volume

The volume of the block can be found by multiplying its three dimensions:

Volume = 5.29 cm x 4.45 cm x 3.34 cm = 81.99 cm^3

So,

Density = 882.2 g / 81.99 cm^3

= 10.77 g/cm^3 (rounding to two significant figures)
