Question

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

Answer 1

Answer: Option (b) is the correct answer.

Explanation:

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

Mathematically,    Density = $\frac{mass}{volume}$

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 = $\frac{mass}{volume}$

                75.0 g/ml = $\frac{mass}{12 ml}$    

               mass = 900 g

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

Answer 2

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
