Answer: For this homework question, you’ll need to look up the molar mass of AgNO₃. Use this to calculate the number of moles in the sample.
Then note that silver is (quite usually) univalent, so there will be as many moles of AgCl as there were of AgNO₃.
Ask your instructor or tutor for more in-depth training, if need be. Good luck!
Explanation:
The molarity of the solution is 0.260 M
<u><em>calculation</em></u>
step 1: calculate the moles of NaOH
moles = mass÷ molar mas
= 5.20 g÷ 40.00 g/mol= 0.13 moles
Step 2: find the molarity of solution
molarity = moles÷volume in liters
=0.13 moles÷ 0.500 L = 0.260 M
