A solution of hno3 is 5 % (w/w)%. Find the mass of hno3 present in 100...
Given that,
A solution of 
is 5%.
Let the volume of solution is x.
We know that,
Density of solution :
Density of solution is equal to the mass of solution divided by volume of solution.
In mathematically form,
Put the value into the formula
We need to calculate the mass of HNO₃ present in 100 ml
Using formula for mass of HNO₃
For, 71.4 ml = 5g of HNO₃
Hence, Mass of HNO₃ present in 100 ml of solution is 7g..

A solution of hno3 is 5 % (w/w)%. Find the mass of hno3 present in 100...
Solution:
Given,
w/w% = 5%
Density (d) = 1.4 g/mL
Volume (V) = 100 mL
To find mass of HNO3 present in 100 mL of solution, we will use the given formula:
w/w% = d * 10 * %mass/molar mass
Let's substitute the given values in the formula:
5% = 1.4 * 10 * %mass/63
Simplifying the formula, we get:
%mass = (5/140) * 63
%mass = 2.25 g
Therefore, the mass of HNO3 present in 100 mL of the solution is 2.25 g.
Explanation:
The given problem can be solved using the formula of weight/weight percent concentration. In this formula, we use the density of the solution and molar mass of the solute to find the percent mass of the solute in the solution. The formula can be written as:
w/w% = d * 10 * %mass/molar mass
Where,
w/w% = weight/weight percent concentration
d = density of solution
%mass = percent mass of solute in the solution
molar mass = molar mass of solute
In this problem, we are given the weight/weight percent concentration of the solution, density of the solution and molar mass of HNO3. We can use these values to find the mass of HNO3 present in the solution.
We substitute the given values in the formula and solve for %mass. Once we find the percent mass, we can calculate the mass of HNO3 present in 100 mL of the solution.
Given,
w/w% = 5%
Density (d) = 1.4 g/mL
Volume (V) = 100 mL
To find mass of HNO3 present in 100 mL of solution, we will use the given formula:
w/w% = d * 10 * %mass/molar mass
Let's substitute the given values in the formula:
5% = 1.4 * 10 * %mass/63
Simplifying the formula, we get:
%mass = (5/140) * 63
%mass = 2.25 g
Therefore, the mass of HNO3 present in 100 mL of the solution is 2.25 g.
