A sample of seawater has a mass of 158g and a volume of 156mL. What is its density?

Answers

A sample of seawater has a mass of 158g and a volume of 156mL. its density is 1.012 g/mL.

According to the question the data are given is as follows:

volume of sea water = 156 mL

mass of sea water = 158 g

density of sea water can be calculated by the following formula :

D = M / V

where,

D = density

M = mass of sample

V = volume of sample

substituting all the value in the given formula , we get :

D = 158 g / 156 mL = 1.012 g/mL

Density of seawater = 1.012 g / mL

Thus, A sample of seawater has a mass of 158g and a volume of 156mL. its density is 1.012 g/mL .
