Reference no: EM13708648

Question- A solution containing 8.92g of KBr in 500.0 mL of solution and has an osmotic pressure of 6.97 atm at 25 degree celsius. Calculate the van't Hoff facter (i) for KBr at this concentration.

I saw the similar question at this website but the explanation was not sufficient. Could you explain it specifically?
