Answer:
Mass % of the solution = 7.1067 %
Explanation:
Given :
Molarity of nitric acid solution = 1.85 M
Density of the solution = 1.64 g/mL
<u>Molarity of a solution is defined as the number of moles of solute present in 1 liter of the solution.</u>
Lets, consider the volume of the solution = 1 L
Thus,
Moles of nitric acid present in the solution:
So,
Moles of Nitric acid = 1.85 moles
Molar mass of nitric acid = 63 g/mol
The mass of Nitric acid can be find out by using mole formula as:
Thus,
<u>Mass of Nitric acid = 116.55 g</u>
Also,
Given : Density = 1.64 g/mL
Also, 1 L = 10³ mL
Volume of the solution is 1000 mL
So, mass of the solution:
<u>Mass of the solution = 1640 g</u>
Mass % is defined as the mass of solute in 100 g of the solution. The formula for the calculation of mass % is shown below:
So,
<u>Mass % = 7.1067 %</u>
