1. Assume that you have 100 g (1 g = 1%) of sample, calculate the moles for each element by dividing the mass by the molar mass (n = m/M). For C it will be 3.33 moles, H will be 6.60 moles, and O will be 3.33 moles. Next divide the number of moles for each element by the smallest value for moles, basically we are finding ...
