- Given that the relative molecular mass of potassium chloride (KCl) is 74.5513 g mol-1, calculate the concentration of potassium chloride solution which will be iso-osmotic with tears (305 mOsM). State your answer in both molar concentration (mol/L) and in percentage (g/100 mL). Please answer very soon will give rating surelyEstimate the total osmolarity of a 2-in-1 TPN bag containing D14W AA 6% plus 160 mEq KCI and 140 mEq NaCl of electrolytes in a total volume of 2 liters. Express final answer in terms of mOsm/LDoes 30% NaCl (MW=58.44g/mol,ionic) have the same, increased, or decreased osmotic pressure as 30% sodium phosphate? Why?
- A 68-year-old lady with bowel cancer who had been admitted to hospital following a fall had a persistent low plasma sodium including the following plasma results (refer- ence ranges are given in brackets): Sodium Potassium Urea Creatinine Glucose Osmolality 120 mmol/L 3.9 mmol/L 3.4 mmol/L 53 μmol/L 5.2 mmol/L 255 mOsm/kg (135-145) (3.5-5.0) (3.5-6.6) (70-150) (3.5-5.5) (285-305) In this patient, the urine volume was low and relatively concentrated, the urine osmo- lality was 374 mOsm/kg and its sodium concentration was 75 mmol/L. Comment on these results.A 5% dextrose is isoosmotic to plasma. What effect would infusion of 1L of a 5% dextrose solution have on ECF and ICF volumes? How it would affect body fluid osmolality of a 70 kg individual and why?The normal range of the sodium electrolyte in the body is 134 to 145 mEq/L. The term mEq is dependent on the charge of the ion. Since sodium is a +1 ion, 134 mEq/L is the same as 134 mmol/L. An ion that has a greater positive or negative charge; however, will have 1 mEq for each positive or negative charge of the ion for every 1 mmol. For example, for Ca+2, 2mEq/1mmol. If the standard range of Magnesium in the body is 0.70 to 0.95 mmol/L, convert this value into mEq/L for the Mg2+ ion. (Use dimensional analysis to figure this out)
- Will weighs 80 kg and his plasma osmolarity is 280 mOsm/L. He eats a salty snack containing 250 mM NaCl and drinks 1L of an energy drink containing 50 mM of electrolytes. Calculate the new plasma osmolarity and intracellular fluidGout is caused by an error in metabolism that leads to abuildup of uric acid in body fluids, which is deposited as slightlysoluble sodium urate (C₅H₃N₄O₃Na) in the joints. If the extra-cellular [Na⁺] is 0.15 Mand the solubility of sodium urate is0.085 g/100. mL, what is the minimum urate ion concentration(abbreviated [Ur⁻]) that will cause a deposit of sodium urate?Write a net ionic equation that shows how this buffer neutralizes added acid (HCl).
- Buffer systems can absorb hydrogen ions from the blood to increase pH into homeostatic range (pH: 7.35 to 7.45)During what condition would buffer systems do this?5. The osmolarity of a 120 mM MgCl2 is: 360 mOsm 0.36 mOsm 240 mOsmEstimate the osmotic pressure of a solution of 0.1 M NaCl at 25°C. Assume 100% ionization of solute.
