Question

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) ___ ml (round your answer to 3 significant figures)

Explanation:

Step1: Find mass of liquid Z

Mass of liquid Z = Total mass - Mass of cup
$m = 50.7 - 15.92=34.78$ g

Step2: Calculate volume of liquid Z

Using the formula $V=\frac{m}{
ho}$, where $
ho$ is density.
$V=\frac{34.78}{0.9237}\approx37.7$ mL

Answer:

37.7
