Questions & Step-by-Step Solutions
What is the osmotic pressure of a solution containing 0.5 moles of glucose in 1 liter of solution at 25 °C? (R = 0.0821 L·atm/(K·mol))
Step 1: Identify the formula for osmotic pressure, which is π = nRT/V.
Step 2: Determine the values needed for the formula: n (number of moles) = 0.5 moles, R (ideal gas constant) = 0.0821 L·atm/(K·mol), T (temperature in Kelvin) = 25 °C + 273 = 298 K, and V (volume in liters) = 1 liter.
Step 3: Plug the values into the formula: π = (0.5 mol)(0.0821 L·atm/(K·mol))(298 K)/(1 L).
Step 4: Calculate the product of n, R, and T: (0.5)(0.0821)(298) = 12.3.
Step 5: Since the volume is 1 liter, the osmotic pressure π = 12.3 atm.
