Question

What is the mass of a steel cylinder that has a density of 75.0 g/mL and a volume of 12 mL?

A. 6.25 g
B. 900 g
C. 87 g
D. 63 g

Answer 1

hey there!:

density = 75.0 g/mL

Volume = 12 mL

mass = ?

Therefore:

D = m / V

75.0 =m / 12

m = 75.0 * 12

m = 900 g

Answer B

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

We know that density is defined as mass divided by volume of the substance.

Mathematically, Density =
`(mass)/(volume)`

It is given that density of given cylinder is 75.0 g/ml and its volume is 12 ml. Therefore, calculate its mass as follows.

Density =
`(mass)/(volume)`

75.0 g/ml =
`(mass)/(12 ml)`

mass = 900 g

Thus, we can conclude mass of a steel cylinder is 900 g.
