Asubstance has 55.80% carbon, 7.04% hydrogen, and 37.16% oxygen. what is it's empirical and molecular formula if it has a molar mass of 301.35 grams

The empirical formula is   and molecular formula is  

Solution : Given,

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of C = 55.80 g

Mass of H = 7.04 g

Mass of O = 37.16 g

Step 1 : convert given masses into moles.

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C =

For H =

For O =

The ratio of C : H : O= 2:3:1

Hence the empirical formula is  

The empirical weight of = 2(12)+3(1) +1(16)= 43g.

The molecular weight = 301.35 g/mole

Now we have to calculate the molecular formula.

Thus molecular formula will be

idk what is it? is this a question that you know the answer or u dont
