A 50.0 mL volumetric flask filled with aqueous solution of
hydrogen peroxide has a total mass of 88.5 g. The mass of the
volumetric flask is 16.5 g. What is the density of the aqueous
solution of hydrogen peroxide?
_g/mL

We have that the density of the aqueous  solution of hydrogen peroxide is

From the Question we are told that

Volume

Mass

Mass of the  volumetric flask 16.5 g.

Generally the equation for density  is mathematically given as

1.44g/mL

Explanation:

Data obtained from the question include:

Volume of volumetric flask = 50mL

Mass of volumetric flask + hydrogen peroxide = 88.5g

Mass of volumetric flask = 16.5g

Mass of Hydrogen peroxide = 88.5 — 16.5 = 72g

The density of aqueous hydrogen peroxide can be obtained as shown below:

Mass of Hydrogen peroxide = 72g

Volume of Hydrogen peroxide = 50mL

Density =?

Density = Mass /volume

Density = 72/50

Density = 1.44g/mL
