What quantity equals mass divided by volume and has the unit g/mL?

What quantity equals mass divided by volume and has the unit g/mL?

• A. Density
• B. Mass
• C. Volume
• D. Weight

Answer: (A)

Density is the amount of matter per unit volume, defined as mass divided by volume. When mass is measured in grams and volume in milliliters, the resulting unit is grams per milliliter (g/mL), which is exactly the density. Mass simply measures how much matter there is; volume measures how much space it occupies; weight is the gravitational force on the mass. So the quantity that equals mass divided by volume and has the unit g/mL is density.
