To calculate the osmotic pressure of a solution, you can use the formula:
π = MRT
Where:
π = osmotic pressure (in atm)
M = molarity of the solute (in mol/L)
R = ideal gas constant (value is 0.0821 L·atm/(mol·K))
T = temperature (in Kelvin)
Given:
Molarity (M) = 0.1M
Temperature (T) = 25°C = 25 + 273 = 298 K
Ideal gas constant (R) = 0.0821 L·atm/(mol·K)
Substituting the values into the formula:
π = (0.1)(0.0821)(298)
π = 2.433 atm
Therefore, the osmotic pressure of the 0.1M NaCl solution at 25°C is approximately 2.433 atm.
To calculate the osmotic pressure, you can use the formula:
Osmotic Pressure (π) = Molarity (M) * Gas Constant (R) * Temperature (T)
First, let's convert the temperature from Celsius to Kelvin:
T (Kelvin) = T (Celsius) + 273.15
T = 25 + 273.15 = 298.15 K
Next, we need to calculate the molarity of the NaCl solution:
Molarity (M) = 0.1 M
The gas constant (R) has a value of 0.0821 L·atm/mol·K.
Now, we can plug in the values into the formula:
π = 0.1 M * 0.0821 L·atm/mol·K * 298.15 K
Calculating this, we get:
π = 2.467 atm
Therefore, the osmotic pressure of a 0.1M NaCl solution at 25 degrees Celsius is approximately 2.467 atm.
