Dextrose 5% in Normosol M Solution (D5NM) is a hypertonic solution that is non pyrogenic and is a nutrient replenisher. In each 1000mL of D5NM, it contains 234mg of sodium chloride. Calculate the osmolar concentration of sodium chloride, in terms of milliosmoles, represented by 500mL of D5NM.
My attempt was
1000mL of D5NM/234mg of NaCl = 500mL of D5NM/ xmg of NaCl
x = 117mg of NaCl
and now stuck with it
