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

  • Chemistry -

    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
