Explanation:

Question 7

Density is defined as the mass of a substance per unit volume. So the formula is mass divided by volume. Option a is volume times mass (incorrect), b is mass times weight (incorrect), c is volume over mass (incorrect), d is mass over volume (correct).

A meter stick measures length (a incorrect), a graduated cylinder measures volume (b incorrect), a bathroom scale measures weight (c incorrect), a triple beam balance is used to measure mass (d correct).

Mass is the amount of matter (a incorrect), density is mass per volume (b incorrect), weight is force due to gravity (c incorrect), volume is the space occupied by a substance (d correct).

Answer:

d. Mass/Volume
