An aluminum engine block has a volume of 4.77 L and a mass of 12.88 kg. What is the density of the aluminum in grams per cubic centimeter?

Solution 98P

Given: Mass = 12,88 kg and Volume = 4.77L

Step 1: Conversion of unit

We know,

1 kg =1000 g

1000 mL = 1L

1 cm3 =1 mL

The conversion factors are :, ,

Volume of Al will be = 4.77L x = 4.77 x103 mL

Mass of the Al will be = 12.88 kg x = 12.88 x103 g

Conversion of volume mL to cm3.

Volume of Al will be = 4.77L x = 4.77 x103 mL x

= 4.77 x 103 cm3
