5 Mineral Id Gizmo | PDF | Minerals | Density - Free Printable

Let’s solve this step by step.

We are given:
- Mass of the mineral = 38.4 g
- Initial water volume in graduated cylinder = 10 mL
- Final water volume after adding mineral = 26 mL

Step 1: Find the volume of the mineral.
When you put an object in water, it pushes the water up — that’s called displacement. The amount the water goes up is equal to the volume of the object.

So, volume of mineral = final volume – initial volume
= 26 mL – 10 mL
= 16 mL

Step 2: Use the density formula.
Density = mass ÷ volume

Plug in the numbers:
Density = 38.4 g ÷ 16 mL

Now do the division:
38.4 ÷ 16 = 2.4

So, the density is 2.4 grams per milliliter (g/mL).

Final Answer:
2.4
