What is the molarity of a solution containing 100 moles of nacl dissolved in 10 liters of water?

2 mol/l

10 mol/l

0.5 mol/l

5 mol/l

10 mol/L

Explanation:

Molarity or concentration is given by the formula;

Molarity = Number of moles/Volume in Liters

In this case; number of moles = 100 and Volume = 10 L

Therefore;

Molarity = 100 moles/10 L

             = 10 mol/L

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
