Question

If 234 g of mercury occupies a volume of 30 cm³, what is the density?

A. 7.8 g/cm³
B. 15.6 g/cm³
C. 17.2 g/cm³
D. 30.8 g/cm³

Answer 1

The density of mercury, given a mass of 234 g and a volume of 30 cm³, is calculated to be 7.8 g/cm³, which is option A.

Step-by-step explanation:

To calculate the density of mercury, we use the formula density = mass/volume. Given a mass of 234 g and a volume of 30 cm³, we perform the division:

density = 234 g / 30 cm³ = 7.8 g/cm³

The correct answer from the given options is A. 7.8 g/cm³. This value is consistent with the known properties of mercury, which has a high density due to its heavy atomic mass.
