What is homeostasis and what does it have to do with the body system

Homeostasis is simply keeping the environment under your best control. Much of that is under the auspices of the central nervous system and peripheral nervous system, but also your autonomic system as well (both sympathetic and parasympathetic components). While the blood system helps with maintaining nutrition levels and waste removal, the lymphatic system (with twice the fluid in it than the cardiovascular system) also helps maintain a recycling of materials needed for detoxification and molecular repair production.

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%
