3. Calculate the volume, in mL, of 100.0 g of alcohol, if the density is 0.79 g/mL.

Naya [18.7K]

Answer:

The answer is

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

<h3> $volume = \frac{mass}{density}$ </h3>

From the question

mass of alcohol = 100 g

density = 0.79 g/mL

The volume is

$volume = \frac{100}{0.79} \\ = 126.58227848...$

We have the final answer as

Hope this helps you

What is the density of a piece of metal in g/cm3 if its mass is determined to be 42.20 g and it is in the shape of a cube, with

maria [59]

It's a cube so the volume = edge^3
Volume = 2.5^3 cm^3 = 15.625 cm^3

density = mass / volume = 42.20 / 15.625 = 2.70 You have 3 places of accuracy.

density of object = 2.70 grams / cm^3 <<<<=== answer.
