Gasoline Density Calculation Fun!

How can we calculate the density of gasoline?

Given a 250-ml flask and stopper with a mass of 110.525 g, and a 50.0-ml sample of gasoline pipetted into the flask, how can we find the density of the gasoline?

Calculating Gasoline Density

To calculate the density of gasoline, we first determine the mass of the gasoline and then divide it by the volume to get the density.

Given: Mass of flask and stopper = 110.525 g, Mass of flask, stopper, and gasoline = 146.770 g, Volume of gasoline = 50.0 ml

To find the mass of the gasoline, we subtract the mass of the flask and stopper from the total mass:

Mass of gasoline = Mass of flask, stopper, and gasoline - Mass of flask and stopper

Mass of gasoline = 146.770 g - 110.525 g = 36.245 g

Next, we calculate the density of the gasoline by dividing its mass by its volume:

Density = Mass / Volume

Density = 36.245 g / 50.0 ml

Since 1 ml is equivalent to 1 g, we have:

Density = 36.245 g / 50.0 g = 0.7249 g/ml

Therefore, the density of the gasoline is 0.7249 g/ml. Isn't that super fun and easy?
