Question

A mineral sample has a mass of 75 g. When the sample is dropped

Answer 1

Answer:

3.75 g/mL

Explanation:

Density can be calculated using the following formula:

Density = mass (g) / volume (mL)

You have been given the mass of the mineral sample (75 g). To find the volume, you need to determine the amount of space that the sample takes up when it is placed in the water. This can be done by subtracting the initial water volume from the final water volume.

Volume = Final - Initial

Volume = 40 mL - 20 mL

Volume = 20 mL

Now, you can calculate the density of the mineral sample.

Density = mass / volume

Density = 75 g / 20 mL

Density = 3.75 g/mL

Answer 2

Answer:

Explanation:

Givens

The volume is the tricky part of this question. You are using the graduated cylinder to measure volume. The rise in the reading of the graduated cylinder = the volume of the sample.

Volume = 40 mL - 20 mL = 20 mL

Mass = 75 grams

Formula

Density = mass / volume

Solution

Density = 75 / 20 = 3.75

Answer

Density = 3.75
