1. the heat of fusion for the ice-water phase transition is 335 kj/kg at 0°c and 1 bar. the density of water is 1000 kg/m3 at these conditions, and that of ice is 915 kg/m3. develop an expression for the change of the melting temperature of ice with pressure. use this to compute the freezing point of water in denver, co where the mean atmospheric pressure is 84.6 kpa

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.
