Could someone explain why the empirical formula for uracil is C2H2N2O2? I picked C because C2H2NO wasn't an answer choice.
What was the point of multiplying 0.026 by 8? The question asked for the moles of citric acid (0.026), but I don't get why they multiplied the answer by the moles of hydrogen.
Are these questions typos? I've encountered at least one typo/misprint on every altius FL I've taken so far so I'm honestly not surprised, but I'd like to know if these answers make sense to anyone.
