An element x has a dibrom ide with the empirical formula xbr2 and a dichloride with the empirical formula xci2. the dibromide is completely converted to the dichloride when it is heated in a stream of chlorine according to the reaction $$xbr2 + cl2 → xci2 + br2$$ when 1.500 g xbr2 is treated, 0.890 g xci2 results. (a) calculate the atomic mass of the element x. (b) by reference to a list of the atomic masses of the elements, identify the element x.

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.
