Answer:
Number of moles = 0.002 mol
Explanation:
Given data:
Volume of solution = 13.42 mL
Molarity of solution = 0.1400 M
Number of moles of NaOH = ?
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
Volume of solution:
13.42 mL (13.42 mL×1 L /1000mL = 0.013 L)
by putting values,
0.1400 M = number of moles / 0.013 L
Number of moles = 0.1400 M × 0.013 L
M = mol/L
Number of moles = 0.002 mol
