Question

You have 3.68 lbs of table salt. The density of table salt is 2.2 g/cm^3. What is the volume of the salt in liters?

Answer 1

density = mass/volume

conversion factors are:

1 lb = 454 g

1000 cm³ = 1 liter

 

3.68 lb x 454g/lb = 1670.72 grams 

1670.72 g x 1cm³/2.2 g = 759.42 cm³ = volume in cm³

759.42 cm³ x 1 liter/1000 cm³ = 0.75942 liters = volume in liters

Answer would be 0.76 liters (2 significant figures)
