Question

A chunk of solid calcium has a mass of 250g and when dropped into water it displaces the water in the graduated cylinder from 35mL to 196mL. What is the density of calcium?

Answer 1

The answer is

1.55 g/mL

Step-by-step explanation:

The density of a substance can be found by using the formula

`density = (mass)/(volume) \\`

From the question

mass of calcium = 250 g

volume = final volume of water - initial volume of water

volume = 196 - 35 = 161 mL

It's density is

`density = (250)/(161) \\ = 1.552795031...`

We have the final answer as

1.55 g/mL

Hope this helps you
