The density of liquid z is 0.9237 g/ml. a student masses a cup
with a sample of liquid z in it and finds the mass to be 50.7 g.
the mass of the cup alone is 15.92 g. what is the volume of
liquid z in the cup? (volume = mass - density)

37.65mL

Explanation:

Given parameters:

density of liquid  Z = 0.9237g/mL

Mass of liquidZ + mass of cup = 50.7g

Mass of cup= 15.92g

Volume of liquid Z in cup=?

Solution:

 Density is the mass per unit volume of a substance. It is mathematically expressed as shown below:

    Density =

To find the volume of liquid Z, we know the density of the liquid but we dont know the mass yet.

Mass of liquidZ = 50.7g - mass of cup = 50.7g - 15.92g = 34.98g

Therefore:

 Volume of liquidZ =

                               =  

                               = 37.65mL
