Jeanie was taken to the er for heat stroke and dehydration. should she be given it fluids that are hypertonic, isotonic to cytosol

                We will neither give the Hypertonic Solution nor the Isotonic Solution but the patient will be given an Hypotonic Solution.

As the patient is taken for heat stroke and has resulted in dehydration so it means that the water content in the cells of the patient has been decreased and the solute content is being increased. Hence, this case is known as Hypertonicity. So, in order to make the concentration of water and solute balance (Isotonicity) on both sides (inside and outside the cells) we should administer an Hypotonic solution into the patient body. Therefore, the higher concentration of solutes in cells will drag the water content from hypotonic solution and gradually the process will attain an isotonic environment.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"
