A sample is reported to contain 44.0% by weight KHP. If you weigh 1.272 g of sample and dilute to 50.0 mL with DI water, what is the molarity of KHP in the final solution? Let's say you prepared the solution in question 2, but you didn't use a pipet to transfer DI water to the Erlenmeyer flask. Instead, you just poured from your DI wash bottle to the 50 mL line on your flask. Is this a problem? Justify your answer.
