Block A has a mass of 5g and a volume of 15mL. What is the density of block A? Will it float in water (density of water is 1.0 g
iris [78.8K]

Explanation:

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

density =  \frac{mass}{volume}  \\

From the question

mass of block = 5 g

volume = 15 mL

The density of the block is

density =  \frac{5}{15}  =  \frac{1}{3}  \\  = 0.33333333...

We have the final answer as

<h3>0.33 g/mL</h3>

The block will float on water since it's density is less than that of water which is 1 g/mL

Hope this helps you
