A pair of 100mL samples of water are taken from a well bored into a large underground salt(NaCl) deposit. Sample #1 is from the top of the well, and is initially at 32. Sample #2 is from a depth of 50. M, and is initially at 42C. Both samples are allowed to come to room temperature (20. C) and 1atm pressure. An precipitate is seen to form in Sample #1.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
