Question
Give equation to calculate molecular mass of a solute using osmotic pressure method.
Solution
The molecular mass of a solute can be calculated using the osmotic pressure method by using the formula:
π = n/V * R * T
Where:
- π is the osmotic pressure
- n is the number of moles of the solute
- V is the volume of the solution
- R is the ideal gas constant
- T is the temperature in Kelvin
To find the molecular mass (M) of the solute, you can rearrange the formula to:
M = (n * W) / V
Where:
- W is the weight of the solute
So, you first need to find the number of moles (n) using the osmotic pressure formula, and then you can find the molecular mass using the second formula.
