Hugh Palmer · Answer 1

C=52.14% of 100g = 52.14g

H=13.13g

O=34.73g

Talia Mueller · Answer 2

Give the compound a mass of 100 grams, so that the mass of each element is

C=52.14% of 100g = 52.14g

H=13.13g

O=34.73g

convert the mass to moles

divide the mole value by the smallest number of moles calculated

round to nearest whole number, this is the mole ratio / subscripts
