Question

A graduated cylinder reads 23.0 mL of water. After 2.5 gram hexnut dropped into the graduated cylinder, the water level reads 24.7 mL. What is the density of the hexnut?

I have the rest of the formula besides volume. Do I use 23.0 mL or 24.7 mL?

Answer 1

`\huge{\boxed{ 1.47 \: g/mL}}`

Step-by-step explanation:

The density of the hexnut can be found by using the formula;

`density = (mass)/(volume)`

From the question;

mass = 2.5 g

The volume of the hexnut can be found by subtracting the initial volume of water that is 23.0 mL from the final volume which is 24.7 mL.

volume = 24.7 - 23 ml = 1.7 mL

`\therefore \: density = \cfrac{2.5}{1.7} \\ = 1.47`
