The volume strength of 1.5 N H2O2 is.......
To determine the volume strength of 1.5 N H2O2 (hydrogen peroxide), we need to understand what "1.5 N" means.
"N" in this context refers to normality, which is a unit of concentration. Normality is defined as the number of equivalents of a substance per liter of solution.
To calculate the volume strength of 1.5 N H2O2, we need to convert the normality into another unit of concentration, such as molarity (M) or percent (%).
H2O2 has a molar mass of approximately 34 g/mol. Since 1 N H2O2 contains 1 equivalent of H2O2 per liter, we can calculate the molarity (M) by using the molar mass.
To convert from normality to molarity, multiply the normality (N) by the molar mass (in g/mol) of H2O2.
For example, to calculate the molarity of 1 N H2O2:
Molarity = Normality (N) × Molar mass (g/mol)
Molarity = 1 N × 34 g/mol = 34 M
Once we have the molarity value, we can calculate the volume strength by multiplying the molarity by the molar mass of H2O2 and dividing by the density of the solution.
Since the density of the solution is not provided in the question, we are unable to provide the exact volume strength of 1.5 N H2O2. The volume strength will depend on the density of the specific solution.
The volume strength of a solution is typically expressed as a percentage or molarity. In the case of hydrogen peroxide (H2O2), the volume strength is commonly given as a percentage. However, you have provided the concentration in units of N (normality). Normality represents the number of equivalents of solute per liter of solution.
To convert the normality of hydrogen peroxide to volume strength, we need to know the molar mass of H2O2, which is approximately 34.02 g/mol.
Using this information, we can follow these steps:
Step 1: Determine the number of moles of H2O2 in the solution.
To find the number of moles, we use the formula:
moles = (normality * volume liters) / 1000
Step 2: Calculate the grams of H2O2 in the solution.
To do this, we multiply the number of moles by the molar mass:
grams = moles * molar mass
Step 3: Convert grams to milliliters (ml) to get the volume strength.
Since the density of water is approximately 1 g/ml, we can assume that the solution consisting mostly of water has a similar density. As a result, the grams of H2O2 approximately equals the volume in milliliters (ml).
Therefore, the volume strength of 1.5 N H2O2 is approximately 1.5 ml.
One molar of H2O2 is two normal.
So 1.5N is 0.75M.
The volume strength of a hydrogen peroxide solution is the volume of oxygen gas that can be liberated by decomposing one litre of the solution (at standard temperature and pressure).
1 mole of O2 occupies 22.4L at STP.
2 H2O2(aq) = 2 H2O(l) + O2(g)
Find how many litres of O2 can be liberated by 1 litre of 1.5N H2O2.
