Question

the density of liquid a is 1.0240 g/ml. a cup with a sample of liquid a in it weighs to be 45.66 g. the mass of the cup alone is 12.32 g. what is the volume of liquid a in the cup? ___ ml

Explanation:

Step1: Find mass of liquid A

$m = 45.66 - 12.32=33.34$ g

Step2: Use density - mass - volume formula

We know that $
ho=\frac{m}{V}$, so $V = \frac{m}{
ho}$. Substituting $m = 33.34$ g and $
ho=1.0240$ g/mL, we get $V=\frac{33.34}{1.0240}=32.56$ mL

Answer:

32.56
