What mass of sucrose should be combined with 524 g of water to make a solution with an osmotic pressure of 8.50 atm at 270 K? I keep working this and end up with 68.81g but it is not right, any help?

Assuming the density of water is 1.00 g/cc (which it is not at this concn of sugar solution), 68.81 g is correct. The problem may be that you are reporting to 4 significant figures and you are allowed only three. Try 68.8 g. If that doesn't take care of it, you need the density of water.
