Question

question 9
the relationship of osmotic pressure and the number of solute(solid) particles in a solution is th
a greater the number of solute particles, the greater the osmotic pressure
b lower the number of solute particles, the greater the osmotic pressure
c greater the osmotic pressure, the lower the numbe of solute particles
d greater the number of solute particles, the lower the osmotic pressure

Explanation:

Osmotic pressure is a colligative property. Colligative properties depend on the number of solute particles in a solution. The formula for osmotic pressure is \(\pi = iMRT\), where \(i\) is the van't Hoff factor (related to the number of particles from dissociation), \(M\) is the molarity (moles of solute per liter of solution, which is related to the number of solute particles), \(R\) is the gas constant, and \(T\) is the temperature. As the number of solute particles (\(iM\) term) increases, the osmotic pressure (\(\pi\)) increases.

Answer:

A. greater the number of solute particles, the greater the osmotic pressure
