6. A commonly purchased disinfectant is a 3.0% (by mass) solution of hydrogen peroxide (H2O2) in water. Assuming the density of the solution is 1.0g/cm3, calculate the molarity andmolality of H2O2
The molarity (M) of the solution is 0.88 mol/L (M)
The molality (m) of the solution is 0.907 mol/kg (m)
Further Explanation:
The problem is about molarity and molality. Both terms are used to describe the concentration of a solution.
Molarity (M) is the number of moles of solute over the Liters of the solution.
Molality (m) is the number of moles of solute over the kilogram of solvent.
Given:
H2O2 is 3% by mass.
Density of solution is 1.0g/cm3
Asked:
Molarity and molality of the solution.
Formula:
Molarity (M) = moles of SOLUTE / Liters of SOLUTION
Molality (m) = moles of SOLUTE / kilogram of SOLVENT
Solution:
*The problem indicates that the H2O2 present in the solution is 3% by mass, it means that in a 100 g of solution there is 3 g of H2O2.
Molarity (M) = moles of SOLUTE / Liters of SOLUTION
Let us look for the moles of solute first: (n= number of moles)
n of H2O2= given mass / molar mass
n= 3 g / 34.0147 g/mol
= 0.088 mol of H2O2
Let us look for the volume of solution: *total mass is 100 % = 100g
Liters of solution = total mass / density
= 100 g / 1.0g/cm3
= 100 cm3 *(1 cm3 = 1ml)
= 100 ml *(1 L = 1000 ml)
= 0.1 L
Let us input all the data into the formula
Molarity (M) = moles of SOLUTE / Liters of SOLUTION
= 0.088 mol of H2O2 / 0.1 L
= 0.88 mol/L (M)
Molality (m) = moles of SOLUTE / kilogram of SOLVENT
The moles of solute was already calculated earlier which is 0.088 mol of H2O2.
Since we know that the solute has 3% by mass, we can say that the remaining 97 % is from the solvent. 97 % by mass means 97 g. Let us convert.
Kilogram of solvent= 97 g / 1000kg (1kg = 1000g)
= 0.097 kg
Let us input all the data into the formula
Molality (m) = moles of SOLUTE / kilogram of SOLVENT
= 0.088 mol / 0.097 kg
= 0.907 mol/kg (m)
Answer:
0.88 mol/L (M)
0.907 mol/kg (m)

2. In its pure form, it is a very pale blue[5] liquid, slightly more viscous than water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3–6% by weight) in water for consumer use, and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or "high-test peroxide", decomposes explosively when heated and has been used as a propellant in rocketry.[6]

14. A solution of hydrogen peroxide is 15.2% by mass. What is the Molarity of the solution? Assume that the solution has a density of 1.01g/mL
Solution:
Step 1: Determine the mass of solute and mass of solution.
In 15.2% by mass, there are 15.2 g of solute in 100.0 g of solution.
Step 2: Calculate the volume of solution.
[tex]\text{volume of solution} = \frac{\text{mass of solution}}{\text{density of solution}}[/tex]
[tex]\text{volume of solution} = \frac{\text{100.0 g}}{\text{1.01 g/mL}}[/tex]
[tex]\text{volume of solution = 99.01 mL = 0.09901 L}[/tex]
Step 3: Calculate the molar mass of solute.
molar mass = (1.008 g/mol × 2) + (16.00 g/mol × 2)
molar mass = 34.016 g/mol
Step 4: Calculate the number of moles of solute.
[tex]\text{moles of solute = 15.2 g H₂O₂} × \frac{\text{1 mol H₂O₂}}{\text{34.016 g H₂O₂}}[/tex]
[tex]\text{moles of solute = 0.44685 mol}[/tex]
Step 5: Calculate the molarity of solution.
[tex]\text{molarity} = \frac{\text{moles of solute}}{\text{volume of solution (L)}}[/tex]
[tex]\text{molarity} = \frac{\text{0.44685 mol}}{\text{0.09901 L}}[/tex]

15. molecular mass of hydrogen peroxide in grams
The molecular formula of hydrogen peroxide is H2O2, which means it is made up of two hydrogen atoms and two oxygen atoms. To calculate its molecular mass in grams, we need to add up the atomic masses of each of these atoms, which can be found on the periodic table:
Atomic mass of hydrogen (H) = 1.008
Atomic mass of oxygen (O) = 15.999
So, the molecular mass of hydrogen peroxide (H2O2) can be calculated as:
2(atomic mass of hydrogen) + 2(atomic mass of oxygen) = 2(1.008) + 2(15.999) = 34.014
Therefore, the molecular mass of hydrogen peroxide is approximately 34.014 grams per mole.

3. Hydrogen peroxide (Agua oxigenada) commonly used as disinfectant for cleaning kitchen counters. If you bought 100 grams of hydrogen peroxide solution with 3% concentration, what is the mass of the hydrogen peroxide?
Solution:
We can obtain the mass of hydrogen peroxide by just simply multiplying the percentage to the total mass of the solution. So:
mass of H2O2 = 100 x 3% = 100 x 0.03 = 3 grams
Therefore, the mass of hydrogen peroxide in the solution is 3 grams.
