SOLVED: In a laboratory experiment, a 15.0-mL sample of KCl solution is poured into an evaporating dish with a mass of 24.10  g. The combined mass of the evaporating dish and KCl solution is 41.50  g. After heating, the evaporating dish and dry KCl have a combined mass of 28.28 g. (9.4) a. What is the mass percent (m / m) of the KCl solution? b. What is the molarity (M) of the KCl solution? c. If water is added to 10.0  mL of the initial KCl solution to give a final volume of 60.0  mL, what is t

SOLVED: A student decides to change the procedure fora lab, attempting to determine the mass of naphthalene in thesample by collecting the solid scrapings from the evaporating dishand weighing them directly (as opposed to weighing the beakerbefore and after sublimation).1) Will weighing the collected (scraped) naphthaleneyield a better result than the original procedure? explainwhy?

In a laboratory experiment, a 10.0 -mL sample of NaCl solution is poured into an evaporating dish with a mass of 24.10 g. The combined mass of the evaporating dish and NaCl solution is 36.15 g . After heating, the evaporating dish and dry NaCl have a combined mass of 25.50 g .(9.4) a. What is the mass percent (m / m) of the NaCl solution? b. What is the molarity (M) of the NaCl solution? c. If water is added to 10.0 mL of the initial NaCl solution to give a final volume of 60.0 mL, what is the m
