Question

If the density of a certain alcohol is 0.785 g/mL, what volume of the alcohol would have a mass of 75.0 g

Answer 1

Answer:

95.54mL

Explanation:

To calculate the volume that would have that mass, what is needed to be done is to use the formula that relates mass, density and volume.

Mathematically,

mass = density * Volume

But in this particular question we are to calculate the volume, we already have the mass and the density.

Rearranging the equation gives the following:

volume = mass/density

Our mass here is 75.0g while our density is 0.785g/mL

Hence, volume = 75/0.785 = 95.54mL

Answer 2

Answer:

The alcohol has a volume of 95.5 mL or 0.0955 L

Explanation:

Step 1: Data given

Mass of the alcohol = 75.0 grams

Density of the alcohol = 0.785 g / mL

Step 2: Calculate the volume of the alcohol

Density = mass of the alcohol / volume of the alcohol

⇒ with mass = 75.0 grams

⇒ with volume = TO BE DETERMINED

⇒ with Density = 0.785 g/mL

Volume = Mass / density

Volume = 75.0 grams / 0.785 g/mL

Volume = 95.5 mL

The alcohol has a volume of 95.5 mL or 0.0955 L
