1) Dose to be given to the patient = 7 * 67 = 449 mg = 0.5 gram
Number of moles of FeSO4 = 875/ 400 = 2.19 milimoles
So number of Fe3+ equivalents = 2 * 2.19 = 4.38 mEq
So 4.38 mEq in 10 ml
875 mg in 10 ml of solution
500 mg in = 10*500/875 = 5.71 ml of the solution
Number of equivalents in 5.71 ml = 4.38* 5.71 / 10= 2.5 mEq
2)30% solution means 30 gram of CaCl2 in 100 ml of solution.
Number of moles in 30 gram =30/111 = 0.27
So number of moles in 1 L= 0.27 * 10 = 2.7
Osmolarity = 2.7 Osm/L = 2700 mOsm/L
So it is much higher (around 9-10 times) than the plasma Osmolarity.

A 67 kg patient is in need of intravenous iron supplementation. She was ordered to receive a single intravenous 7 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 875 mg of stabilized iron sulfate salt in water to produce 10 mL of solution. How many milliequivalents of iron (Fe 3+) will the patient receive as a single dose? Assume the...
A 58 kg patient is in need of intravenous iron supplementation. She was ordered to receive a single intravenous 5 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 975 mg of stabilized iron sulfate salt in water to produce 10 mL of solution. How many milliequivalents of iron (Fe 3+) will the patient receive as a single dose? Assume the...

A 71 kg patient is in need of intravenous iron supplementation. He was ordered to receive a single intravenous 6 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 800 mg of stabilized iron sulfate salt in water to produce 20 mL of solution. How many milliequivalents of iron (Fe 3+) will the patient receive as a single dose? Assume the...
A 71 kg patient is in need of intravenous iron supplementation. She was ordered to receive a single intravenous 10 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 750 mg of stabilized iron sulfate salt in water to produce 25 mL of solution. How many milliequivalents of iron (Fe 3+) will the patient receive as a single dose?
I have 2 different questions!!

how many milliequivalents?
what is the osmolarity of this solution?
A 66 kg patient is in need of intravenous iron supplementation. She was ordered to receive a single intravenous 5 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 750 mg of stabilized iron sulfate salt in water to produce 25 mL of solution. How many milliequivalents of iron (Fe 3+)...
answer for this question should be in MEq not ml
answer should be in units of mOsmol/L
A 71 kg patient is in need of intravenous iron supplementation. She was ordered to receive a single intravenous 9 mg/kg dose of iron (III) sulfate (ferric sulfate - Fe2(SO4)3 - MW=399.88 g/mol). Iron (III) sulfate was prepared as a stabilized aqueous solution for this patient by dissolving 975 mg of stabilized iron sulfate salt in water to produce 15 mL of solution....
A patient is ordered to receive sodium supplementation by intravenous infusion of a sodium carbonate solution [Na2CO3 , MW=105.989 g/mol]. The patient is ordered to receive 0.8 mEq of Na + ions per hour. A 750 mL intravenous bag is prepared that contains 27 mL of a 4.2% solution of sodium carbonate. What should be the infusion rate (in units of mL/min) necessary to produce the ordered dose of 0.8 mEq/hr of sodium? (Note: Consider the total solution volume to...
A patient is ordered to receive chloride supplementation by intravenous infusion of a sodium chloride solution [Na Cl MW-58.44 g/mol]. The patient is ordered to receive 0.4 mEq of Cl - ions per hour. A 1000 mL intravenous bag is prepared that contains 12 mL of a 23.4% solution of sodium chloride. What should be the infusion rate (in units of mL/min) necessary to produce the ordered dose of 0.4 mEq/hr of chloride? (Note: Consider the total solution volume to...
