Question

A plastic material has a mass of 3.48 g and a volume of 10 mL.

Will it float or sink? Why?

Answer 1

It will float because it is less denser than water.

Step-by-step explanation:

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

• ρ =
  `(m)/(V)` , where ρ refers to density, m refers to mass and V refers to volume

Water has a constant density of 1 gram per cm-cubed or 1 gram per
`cm^(3) \frac{}{}`.

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

• ρ = what is being asked
• mass (m) = 3.48 grams
• Volume (V) = 10 ml (or 10
  `cm^(3)`)

Let's see the answer: ρ =
`(3.48 g)/(10 ml)` = 0.348
`(g)/(ml)` (density of the plastic material)

Since 0.348
`(g)/(ml)` is lesser than 1
`(g)/(ml)`, then this makes it less denser than water. Thus, it is going to float.
