A solution contains 72% water d 28% methyl alcohol. Calculate the mole firaction of each component in the solution.

Find the mole fraction of 10% NaOH solution.

Explain the terms molecularity and order of a reaction. Give one example from each of first and second order reactions. A 0.1 M HCN solution contained 0.2 moles of KCN per litre of the solution. What was the hydronium ion concentration of the solution. (K_(a) for HCN = 7.2 xx 10^(-10) )
