Percent mass to volume

Intravenous solutions—those that are administered directly into a patient s veins— must have osmotic pressure equal to that of bodily fluids. These solutions are called isoosmotic. When a patient is given an IV in a hospital, the majority of the fluid is usually an isoosmotic saline solution—a solution containing 0.9 g NaCl per 100 mL of solution. In medicine and in other health-related fields, solution concentrations are often reported in units that indicate the mass of the solute in a given volume of solution. Also common is percent mass to volume—which is the mass of the solute in grams divided by volume of the solution in milliliters times 100%. In these units, the concentration of an isoosmotic saline solution is 0.9% mass/volume. 

CAN YOU ANSWER THIS An isoosmotic sucrose (C12H22O11) solution has a concentration of 0.30 M. Calculate its concentration in percent mass to volume. 

An isotonic solution contains 0.90% NaCl mass to volume. Calculate the percent mass to volume for isotonic solutions containing each solute at 25 °C. Assume a van t Hoff factor of 1.9 for aU ionic solutes.
