34ml ethanol+ 3ml Methanol+ 75 ml water = 112ml solution in a beaker I’ve taken 11ml solution in another beaker. What is the mass% and mole% of water in the 11ml solution? can anyone give me the answer?

hello.
If 11 ml solution is taken from the 112 ml solution, the water concentration in both solutions is the same. If the effect of molecular bonds of the components(ethanol,methanol,water) such as nitrogen bonds is neglected, it is necessary to convert the volume of each component into a mass using density and convert it to mole using molecular weight. The weight percentage of water is 71.915 and the molar percentage is 86.320.

Thank you so much Ra Di. if I add 5 ml propanol with that 11ml solution, will the mol% of water be still same?
