What is the mass of a 4.00cm3 piece of sod chloride having density of 2.16 g/cm3

8.64 g

Explanation: Density is the ratio of mass of substance to its volume. It is calculated by dividing the mass of a substance by its volume. Density = Mass : Volume

In this case we are given,

Volume of sodium chloride = 4.00 cm³

Density of sodium chloride = 2.16 g/cm³

We are required to calculate the mass of sodium chloride,

Rearranging the formula;

Mass = Density * volume

Mass of sodium chloride = 2.16 g/cm³ * 4.00 cm³

= 8.64 g

Therefore, the mass of sodium chloride is 8.64 g
