Question

A solution contains .370 mol of isopropanol (C3H7OH) dissolved in 1.700 mol of water.  A) What is the mole fraction of isopropanol? B) What is the mass percent of isopropanol?  C)The molarity of isopropanol?

DrBob222 · Answer

mole fraction = moles isopropanol/total moles. mass percent = mass isopropanol/100 g solution M = moles isopropanol/L soln.
