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)

Respuesta :

Answer:

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 = [tex]\frac{mass}{volume}[/tex]

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 = [tex]\frac{mass of liquidZ}{density of liquidZ}[/tex]

                               =  [tex]\frac{34.98}{0.9237}[/tex]

                               = 37.65mL

Answer:

37.7
