I am having trouble figuring out the calculations for osmotic pressure. This is what I need to do.
Indicate whether the osmotic pressure of a 0.1M NaNO3 solution will be less than , the same as , or greater than that each of the following solutions
a. 0.1M NaCl b. 0.1M KNO3 c. 0.1M Na2SO4 d. 0.1M Glucose

pi = i*M*R*T
R and T (and M) are constant; therefore, only i will affect pi.
i for NaNO3 = 2
i for KNO3 = 2
i for Na2SO4 = 3
i for glucose = 1
