Given the following conversions: 4 speegles = 7 toggs
9 gurps = 5 vexes
2 wibbles = 3 zooms
6 vexes = 11 zooms
12 wibbles = 7 yings
15 toggs = 9 yings

Convert 325.00 gurps/speegles = ? yings/toggs

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%
