Answer:
1.44 g/mL
Explanation:
The following information was derived from the provided question:
Volume (V) of H2O2 = 50 mL.
Total mass of flask and H2O2 = 88.5 g.
Mass of the flask = 16.5 g.
What is the density (D)?
Next, we will calculate the mass of hydrogen peroxide (H2O2).
This is determined as follows:
Total mass of flask and H2O2 = 88.5 g.
Mass of the flask = 16.5 g.
What is the mass of H2O2?
Mass of H2O2 = (Total mass of flask + H2O2) – (Mass of flask)
Mass of H2O2 = 88.5 – 16.5
Mass of H2O2 = 72 g
Finally, we will find the density of hydrogen peroxide (H2O2) as follows:
Volume (V) of H2O2 = 50 mL.
Mass (m) of H2O2 = 72 g.
What is the density (D)?
Density (D) = mass (m) divided by volume (V)
D = m/V
D = 72 g / 50 mL
D = 1.44 g/mL
In conclusion, the hydrogen peroxide (H2O2) density is 1.44 g/mL.
