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 4.6 g/mL and its mass is equal to 22 g, what is the volume of the substance?
26.6 mL
101.2 mL
0.21 mL
4.8 mL

Answer 1

Solve the following for V:
4.6 = 22/V

Answer 2

so it's 21.

Answer 3

if
\[D=\frac{ m }{ V}\]

Rearrange that so it is
\[V=\frac{ ? }{ ? } \]

Then put the values from the question for D and m and solve it...

Answer 4

its 21

Answer 5

and it's NOT what you guessed

Answer 6

oh okay 101.2

Answer 7

and there is not an option of 21 anyhow

Answer 8

2 more guesses - 1 of them will be correct

Just DO the sum

Answer 9

4.8

Answer 10

have you written the equation and solved it ?

ONE of the 4 options IS correct
