View the step-by-step solution to:

Osmotic pressure (Os) is a colligative property, for which the relevant equation is Os = MRT If a solution is both 0.0010 M NaCl and 0.

Osmotic pressure (πOs) is a colligative property, for which the relevant equation is

πOs = MRT

If a solution is both 0.0010 M NaCl and 0.0011 M MgCl2, what is the relevant value of M (in M) in this equation, assuming ideal van't Hoff factors?

Top Answer

πOs =  MRT M = (Vant Hoff factor of NaCl * Molarity of NaCl) + (Vant Hoff factor of MgCl2 * Molarity of MgCl2)... View the full answer

  • The work flow is right, but for molarity of NaCl you used 0.0001 instead of 0.0010. Thank you though, it is still helpful!

For ideal van't Hoff factors there is no dissociation of the salts. 0.0010 M NaCl means... View the full answer
