Question

A bottle of 12.0 M hydrochloric acid has only 35.7 mL left in it. What will the HCl concentration be if the solution is diluted to 250.0 mL?

Accepted Answer

Hey everyone, we're asked what is the concentration of a 75 millimeter of 2.50 Moeller per clerk acid solution diluted to 0.500 liters. To answer this question, we can go ahead and use the formula M one V one equals M two V two. And for this formula our units do have to be the same so we can convert our 75.0 mL to liters by using our dimensional analysis and we know that we have 10 to the third milliliters per one leader. This will get us to 0.075 L. Now let's go ahead and plug in our values. So we have 2.50 moller and we're going to multiply this by 0.075 L. This is going to be equal to our second polarity times its volume, which is 0.500 liters, Solving for our polarity. We can go ahead and divide both sides by 0.500 l And this will get us to a more clarity of 0.375 Moller, which is going to be our final answer. So I hope that made sense. And let us know if you have any questions
