2 For your pH titration you now want to weigh an amount of your unknown acid based on your answer to Question 1. However, you do not want to waste a lot of time trying to get the amount exactly. And even if you could, it is not necessary. Let's say you weigh out an amount equal to 513.9 mg (Close Enough But since this amount...
