Which measurements are needed in order to calculate the density of a given object? a. length and width b. mass and weight c. volume and temperature d. mass and volume

Solution:

for calculating the density of any given object we need mass of that object and the volume of that object.

because density is defined as A material's density is defined as its mass per unit volume. It is, essentially, a measurement of how tightly matter is crammed together.

ρ = m / v

therefore the answer is D.

the answer is na (sodium)
