M = mols/L or
mols = M x L = 0.04826 x 0.405 = 0.019545
I think you just reported too few significant figures in the answer. You are allowed three and you reported only two. Of course my answer has too many.
When 3.75 g of a nonelectrolyte solute is dissolved in 405 mL of water at 25 °C, the resulting solution exerts an osmotic pressure of 897 torr.
What is molarity?
I found molarity to be 0.048.
What is the number of moles of solute?
to find moles, I multiplied it by .405 and got an answer of 0.019 moles, however, that's incorrect. What did I do wrong? Please help? Thanks!
