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
Gemiola [76]

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
