Urgent moles calculation help
31.6% carbon
5.3% hydrogen
63.1% oxygen
a) What is the empirical formula of acid X?
b) an aqueous solution contains 11.4 g of X per dm^3. 20 cm^3 of this solution required 30cm^3 of 0.1 mol dm^-3 NaOH for reaction in a titration. calculate the relative molecular mass of the acid
c) deduce the full structural formula of X
