A5 gram ball has a volume of 2.5 milliliters. What is the density of the ball? (Mass is measure in grams, volume is measured in milliliters and density is measured in
grams/milliliter.)

2 g/mL

Explanation:

The following data were obtained from the question:

Mass (m) = 5 g

Volume (V) = 2.5 mL

Density (D) =.?

Density is simply defined as the mass of substance per unit volume of the substance. Mathematically, it is expressed as:

Density (D) = mass (m) /volume (V)

D = m/V

With the above formula, we can obtain the density of the ball as follow:

Mass (m) = 5 g

Volume (V) = 2.5 mL

Density (D) =.?

D = m/V

D = 5/2.5

D = 2 g/mL

Therefore, the density of the ball is 2 g/mL.

i think it is true since you can test the answer and can use observations to complete it.

the answer is c.the valence of the atoms combine .
