Question

4. What is the Osmotic Pressure of a 2.36 Molar Cr(NO3), solution at 293 K? R = 0.0821

Answer 1

113.541

Step-by-step explanation:

Osmotic Pressure Formula:

P = i x Molarity x 0.0821 x Temp. in Kelvins

2 x 2.36 x .0821 x 293 = 113.541

i = the charge of ions the compound will dissociate into.

Cr(NO3) --> Cr+1 + NO3-1

Both ions have 1 charge. This makes 2.
