Question

An unknown object has a mass of 15 g and its volume is 9 cm^3. Calculate the density and determine if the item would sink or float in water.

Answer 1

1.67 g/cm³

Step-by-step explanation:

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

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

From the question we have

mass = 15 g

volume = 9 cm³

`density = (15)/(9) = 1.67 \\`

We have the final answer as

1.67 g/cm³

The object will sink in water since it has a density greater than that of water which is 1 g/cm³

Hope this helps you
