Final answer:
The osmotic pressure of a sodium-chloride solution with the same concentration as an 0.03 molar glucose solution would be higher due to the presence of more solute particles.
Step-by-step explanation:
The osmotic pressure of a solution is determined by the concentration of the solute particles present. In this case, we have an 0.03 molar solution of glucose with an osmotic pressure of 22.0 kPa. To find the osmotic pressure of a sodium-chloride solution with the same concentration and temperature, we need to consider that each mole of glucose adds one mole of solute particles, while each mole of NaCl produces two moles of particles. Therefore, the osmotic pressure of the sodium-chloride solution would be higher due to the presence of more solute particles.
For example, if we have a 0.03 molar NaCl solution, we would have a higher osmotic pressure compared to the 0.03 molar glucose solution because each mole of NaCl produces two moles of particles. However, without knowing the actual concentration of the sodium-chloride solution, we cannot calculate the exact osmotic pressure.
