Question

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/mL) Don't forget the units!! PLSSSS PLSSS PLSSS HELP I WILL MARK BRAINLIEST AND HELP WITH UR QUESTIONS I PROMISE!!!!

Answer 1

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

0.33 g/mL

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
