A 250 ml flask and stopper have a mass of 110.525 g. A 50 ml sample of gasoline is pipetted into the flask, giving a total mass of 146.770 g. Find the density of the gasoline

Verified Answer :

The density of Gasoline will be "0.725 g/mL".

Density:

Given values:

  • Flask's weight = 110.525 g
  • Volume = 50 mL

Now,

  • Gasoline + Flask's weight = \(110.525+50\)

                                                 = \(146.770\) g

Weight of Gasoline will be,

= \(146.770-110.525\)

= \(36.245\) g

hence,

The Density will be:

= \(\frac{Weight}{Volume}\)

By substituting the values,

= \(\frac{36.245}{50}\)

= \(0.725\) g/mL

Thus the above approach is right.
