Answer
28.5 mL ( or 28.5 $cm^{3}$ ) is the volume of bromine.
Work Step by Step
1- We know that density, volume , and mass are related through density formula:
d = $\frac{m}{v}$
By multiplying both sides with v we get an identical equation with this one.
d x v = $\frac{m}{v}$ x v
m = d x v
We now divide by d both sides and we get
v = $\frac{m}{d}$
2- Replace values of mass and density to find the volume .
mass is 88.5 g
density is 3.10 $\frac{g}{cm^{3}}$
(Note: it is important to always check the units before you replace the values in the formulas.)
v = $\frac{m}{d}$
v = $\frac{88.5 g}{3.10 \frac{g}{mL}}$
v = 28.55 mL or v = 28.55 $cm^{3}$
(because 1mL = 1$cm^{3}$)
