Question

how many moles of nacl required to prepare 10 molar aqueous nacl solution

Answer 1

Answer ⇒ 10 moles of NaCl is required to prepare 10 molar solution.

Explanation ⇒ 10 molar aqueous NaCl solution means, 10 moles of NaCl is dessolved in 1 Liter of the solution.

Now, The Question is asked about the no. of moles.

This means, no. of moles that should be required to prepare 10 molar solution is 10 moles.

Listen ! It is not sure.May be the volume of the solution is 0.5 liter, then no. of moles required will be 5. So when Volume of the solution will change no. of moles of the NaCl required will also be change for the same 10 Molar Solution.

But Remember ratio should always be same.

Also, we every time only talk about 1 liter solution and 1 kg of solution while discussing about the concentration.

Hence, no. of moles required will be 10.

Hope it helps.

Answer 2

Answer:

10 molar aqueous NaCl solution means, 10 moles of NaCl is dessolved in 1 Liter of the solution.
