Question

1pt how is the density of ocean water calculated?

a. volume/mass

b. salinity/volume

c. mass/volume

d. salinity/mass

Explanation:

Density is a physical property defined as mass per unit volume. For any substance, including ocean water, the formula for density ($
ho$) is $
ho = \frac{\text{mass}}{\text{volume}}$. Option A is the reciprocal (volume/mass) which is not density. Options B and D involve salinity, but density of ocean water (like any matter) is based on mass and volume, not directly salinity in the basic density formula.

Answer:

C. mass/volume
