# 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?
