The mass of the hydrogen peroxide is 238 g.
Hydrogen peroxide at room temperature stays in liquid form. It has a bitter taste and is colorless. It is an important regent used in pharmaceutical and other industries. It also has medical use. It can be used as an antiseptic.
The number of miles in the hydrogen peroxide is n.
n = 7 mol
The molar mass of hydrogen peroxide is,
The molar mass of hydrogen peroxide = Molar mass of hydrogen + Molar mass of oxygen
= 2 × 1 + 2× 16
= 34 g/mole
The molar mass of hydrogen peroxide is 34 g/mole.
The mass of the hydrogen peroxide is,
[tex]Number \: of \: moles = \frac{ Mass }{ Molar \: mass}[/tex]
[tex]n = \frac{m}{M} [/tex]
m = n × M
m = 7 × 34
m = 238 g.
Therefore, the mass of the hydrogen peroxide is 238 g.
