Oil of wintergreen contains methyl salicylate. Elemental analysis of methyl salicylate found 63.15% carbon, 5.30% hydrogen, and 31.55% oxygen. the mass spectrum determined the molecular weight of mehtyl salicylate to be 125.15 g/mol. What is the molecular formula of methyl salicylate?
Please show all work. I'm stuck on creating the empirical formula. I converted the percentages to moles, but when I tried to create an empirical formula, I couldn't get whole numbers for the subscripts.
Calculate the internal energy change (delta(U)) for vaporization of 100 g of CI2(l) at this temperature and 1 bar? (b) Calculate its molar entropy change (delta(S)) for vaporization at this condition.
how many grams of mercury (II) oxide are needed to create 28.9 grams of oxygen gas?
