How do you find the volume of 15 grams of ethanol?

Answer 1

Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.

Answer 2

mass = volume x densitySolving for volume:

volume = mass / density

So, you basically look up the density of ethanol, then divide the mass by the density.

Answer 3

You have to divide the mass by density to get the volume. Mass is 15 gram. Density of alcohol is 0.789 at 20 degree Celsius. So 15/ 0.789 comes to be 19 ml.
