Answer:
1.44 g/mL
Explanation:
From the question given above, the following data were obtained:
Volume (V) of H2O2 = 50 mL.
Mass of flask + H2O2 = 88.5 g.
Mass of flask = 16.5 g.
Density (D) =?
Next, we shall determine the mass of the hydrogen peroxide (H2O2).
This can be obtained as follow:
Mass of flask + H2O2 = 88.5 g.
Mass of flask = 16.5 g.
Mass of H2O2 =?
Mass of H2O2 = (Mass of flask + H2O2) – (Mass of flask)
Mass of H2O2 = 88.5 – 16.5
Mass of H2O2 = 72 g
Finally, we shall determine the density of the hydrogen peroxide (H2O2) as follow:
Volume (V) of H2O2 = 50 mL.
Mass (m) of H2O2 = 72 g.
Density (D) =?
Density (D) = mass (m) /volume (V)
D = m/V
D = 72 g / 50 mL
D = 1.44 g/mL
Therefore, the density of the hydrogen peroxide (H2O2) is 1.44 g/mL.
