A 0.86% by mass solution of NaCl, an electrolyte, is called 'physiological saline' because its osmotic pressure is equal to that of the solution in blood cells. Calculate the osmotic pressure of this solution at normal body temperature (37C). The density of saline solution at this temperature is 1.005g/mL.
A chemist dissоlves 75 g оf аcetic аcid in enоugh wаter to prepare two litres of solution. a) What is the concentration of H3O+ ions? b) What is the concentration of the acetate ion (the conjugate base)?c) What is the pOH of the solution? Ka of acetic acid = 1.8 x 10-5 You may use the desmos online calculator M = mol/L mass = moles x molar mass pH = -log[H+] [H+] = 10-pH pOH = -log[OH-] [OH-] = 10-pOH
