Question

A jar has a mass of 63 grams and a volume of 45 cubic centimeters. What is the density of the jar?

1) 2.8 g/cm³
2) 1.4 g/cm³
3) 0.7 g/cm³
4) Cannot be determined

Answer 1

The density of the jar with a mass of 63 grams and a volume of 45 cubic centimeters is calculated as 1.4 g/cm³, which is option 2 from the choices given.

Step-by-step explanation:

The question asks to calculate the density of a jar given its mass and volume. Density is defined as the mass-to-volume ratio of a substance. The formula to calculate density is D = m/V, where D is density, m is mass, and V is volume.

In this case, the mass (m) of the jar is 63 grams and the volume (V) of the jar is 45 cubic centimeters. To find the density (D), we divide the mass by the volume:

D = m/V = 63 g / 45 cm³ = 1.4 g/cm³

Therefore, the density of the jar is 1.4 g/cm³, which corresponds to option 2 from the provided choices.
