Answer :
Answer:
Volume of solution is 0.88 L.
Explanation:
Given data:
Molarity of solution = 0.750 M
Mass of KNO₃ = 67.0 g
Volume of solution = ?
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Now we will calculate the number of moles.
Number of moles = mass/molar mass
Number of moles = 67.0 g/ 101.1 g/mol
Number of moles = 0.66 mol
Now we will put the values in molarity formula.
0.750 M = 0.66 mol / L of solution
L of solution = 0.66 mol / 0.750 M
L of solution = 0.88 L
Volume of solution is 0.88 L.
