Answer:
0.047 M
Explanation:
Given data:
Volume of KF = 93.2 mL
Molarity of KF = 2.03 M
volume of water added= 3.92 L
Solution:
First of all we will calculate the number of moles of KF.
number of moles = Molarity × volume in litter
number of moles = 2.03 mol/L × 0.0932 L
number of moles = 0.189 mol
Molarity of solution:
Total volume = 3.92 L + 0.0932 L = 4.0132 L
Molarity = number of moles / volume in litter
Molarity = 0.189 mol/ 4.0132 L
Molarity = 0.047 M
