Question

the mass of a substance varies directly with the volume of the substance the volume of 100 kilograms of the substance is 80 liters. what is the volume of liters of 3.2 kilograms of the substance

Answer 1

Important concepts: Mass varies directly with Volume

Mass = Constant * Volume

Mass = 100 kg

Volume = 80 L

100 = k * 80

100 / 80 = k

1.25 = k

NEW Mass = 3.2 kg

Mass = Constant * Volume

3.2 = (1.25) * V

3.2 / 1.25 = V

2.56 = V

Your answer is 2.56 Liters! Hope that helps!
