10 points!! Please give me work with it and I will mark as brainlist. Answer the question below. Use the rubric in the materials for help if needed.
A compound is 40.0 % C, 53.3 % 0, and 6.66 % H What is its molecular formula if its molecular mass is 60 g? Show all your work.

The molecular formula will be

Explanation:

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 = 40.0 g

Mass of O = 53.3 g

Mass of H = 6.66 g

Step 1 : convert given masses into moles.

Moles of C =

Moles of O =

Moles of H =

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

For C =

For O =

For H =

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

Hence the empirical formula is

The empirical weight of = 1(12)+1(16)+2(1)= 30g.

The molecular weight = 60 g/mole

Now we have to calculate the molecular formula.

The molecular formula will be=

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

where are the choice options?
