A colourless liquid is analysed and found to contain C 59.00%, H 7.15%, N 7.65% and O 26.20%. What is the empirical formula for the compound? Blank 1Do NOT put a 1 after an element if there is 1 of them (write the formula as it would normally be written). Do NOT leave a space between element symbols. Do not use superscripts and subscripts in the formula. Give the formula with elements in the order C H N O.
