Question

1. What two quantities must be known to calculate the density of a sample of matter?

A. color and mass
B. mass and volume
C. length and mass
D. solubility and mass

Answer 1

mass and volume is the answer

Answer 2

remember the formula for density:

`d = (m)/(v)`
where d is density, m is mass, and v is volume.

Therefore, B. mass and volume is needed to determine the density
