Question

The density of a substance describes how much matter is present in one unit of the substance's volume.

The formula for density is

D =
m
V

where m is the mass of the substance and V is the substance's volume.

If the density of a substance is equal to 1.6 g/mL and its volume is equal to 24 mL, what is the mass of the substance?
A. 15 g
B. 25.6 g
C. 0.07 g
D. 38.4 g

Answer 1

use \[d=\frac{ m }{ V }~or~m=V*d\]

Answer 2

d=m/v

Answer 3

\[m=24*1.6=?\]

Answer 4

38.4
