James is preparing three solutions of salt water. each of the solutions has the same amount of water in the beaker and a different amounts of salt. in the first beaker, there is one scoop of salt in the beaker. the second beaker has two scoops of salt. the third beaker has three scoops of salt. which of the beakers is the most dilute solution?

The first one, The less of a substance like salt there is the more diluted the substance but the more there is the more concentrated the substance is

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

fe 55.85 g/mol and h2o 18.02 g/mol.
