Adam added 30.0 grams of Sodium Hydroxide to 750.0mL of water to create a stock solution to be used for a number of purposes. 250.0mL of the stock solution was removed to be used for a demonstration but Mr. Offenbacher decided the initial concentration was too strong. He decided to add another 100.0mL of water to the removed solution. What was the concentration of the initial stock solution and what is the concentration of the final concentration to be used for the demo? Show all of your conversion factors for full marks.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
