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)\n___ ml (round your answer to 3 significant figures)\nenter the answer

Answer

Explanation:

Step1: Calculate mass of liquid Z

Subtract cup - only mass from total mass. $m = 50.7 - 15.92=34.78\ g$

Step2: Calculate volume of liquid Z

Use the volume - mass - density formula $V=\frac{m}{\rho}$. $V=\frac{34.78}{0.9237}\approx37.76\ mL$

Step3: Round to 3 significant figures

$V = 37.8\ mL$

Answer:

$37.8$
