Aplastic material has a mass of 3.48 g and a volume of 10 ml.

will it float or sink? why?

It will float because it is less denser than water.

Explanation:

"Density" refers to the measure of an object's mass per unit volume. It follows the formula below:

Water has a constant density of 1 gram per cm-cubed or 1 gram per .

Now that we know about the formula, it would be best to compute for the plastic material's density.

Let's see the ρ = = 0.348 (density of the plastic material)

Since 0.348 is lesser than 1 , then this makes it less denser than water. Thus, it is going to float.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
