Determine the mass of 2.5 cups of water if the density of water is 1.00 g/cm3 and 1 cup = 240 ml. i
Radda [10]

The mass is simply the product of volume and density. But first, let us convert the volume into cm^3 (cm^3 = mL):

volume = 2.5 cups * (240 mL/cup)

volume = 600 mL = 600cm^3

 

So the mass is:

mass = 600 cm^3 * (1 g / cm^3)

<span>mass = 600g</span>
