Psoln = XH2O*PoH2O
Solve for XH2O
XH2O = (moles H2O/total moles)
Plug in X, n for H2O and n for glucose and solve for n glucose, then
grams glucose = moles x molar mass.
Post your work if you get stuck.
The vapor pressure of water is 23.8 torr. at 25 degrees C. Determine the mass of glucose (molar mass 180g/mol) needed to add to 500g of water to change the vapor pressure to 23.1 torr.
