Press the yellow reset button at the bottom of the simulation screenUnder Constant Parameter , select Volume. Again pump the pump handle once to introduce 40 to 50 gas molecules. Record the pressure in the data table. Use the heat control to heat the gas to each of the other temperatures in the data table, and record the new pressure.

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%

so what is the problem with your lab report and whats the subject of the lab report? i will you
