Question

Dean used a triple beam balance to find that the mass of a rock was 40 g and he used a graduate cylinder that measures the volume is 5 ml. What is the density?

a
9 m/l
b
10 g/ml
c
6 g/ml
d
8 g/ml

Answer 1

The density of the rock that Dean measured is calculated by dividing the mass (40 g) by the volume (5 ml), which results in a density of 8 g/ml.

Step-by-step explanation:

The density of an object is calculated by dividing its mass by its volume. In this case, Dean found the mass of a rock to be 40 g and the volume to be 5 ml. To find the density, the formula used is:

Density = Mass / Volume

Plugging in the values:

Density = 40 g / 5 ml = 8 g/ml

Therefore, the correct answer is (d) 8 g/ml. This is a common calculation in the field of physical science and involves understanding and applying the concept of density, which is a fundamental chemical property of materials.
