A 2.0 mL sample of carbon tetrachloride (CCI4 ) masses at 3.16 g. What is the density of this substance in g/mL? A. 1.5 g/mL
B. 1.58 g/mL
C. 1.6 g/ml
D. 0.63 g/ml

Explanation:

The density of a substance can be found by using the formula

From the question

mass of CCl4 = 3.16 g

volume of CCl4 = 2.0 mL

Substitute the values into the above formula and solve for the Density

That's

We have the final answer as
