Question

A piece of wood with a volume of 489 cm3 and a mass of 153 grams has a density of _______ g/cm3 and will _____ in water.

Answer 1

Rounded to the nearest hundredth, the piece of wood has a density of 0.31 and will float in water.

Step-by-step explanation:

You know that the piece of wood has a density of 0.31 because the formula for density is mass divided by volume, and the density of water is 1.0 g/cm3. And as you know, 0.31 < 1.0, so the wood will float.

Hopes this helps!

Answer 2

Step-by-step explanation:

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

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

From the question

mass of wood = 153 g

volume = 486 cm³

The density is

`density = (153)/(486) = (17)/(54) \\ = 0.3148148148...`

We have the final answer as

0.32 g/cm³

The wood will float on water since it's density is less than that of water which is 1.0 g/cm³

Hope this helps you
