Calculate the empirical formula for compound

ethyl butyrate (pineapple oil): C, 62.04%; H, 10.41%; O, 27.55%

Can someone show me the steps?

check, yes they add to 100

well, let's say we have 100 grams of this stuff

Then we have 62.04 grams of C
62.04 / 12 = 5.17 mols of C

10.41 mols of H

27.55/16 = 1.72 mols of O

10.41/5.17 = 2.01
so 2 H for every C

10.41/1.72 = 6.05
so 6 H for every O

3C 6H 1O or C3H6O

which is half the real (not empirical) molecule C6H12O2

Sure, I can help! But before we start, let's have a little bit of fun. Why did the pineapple go to the party? Because it couldn't resist the "juice"!

Now, let's get serious and tackle the steps to determine the empirical formula for ethyl butyrate, also known as pineapple oil.

Step 1: Convert the percentages into grams.
For every 100g of ethyl butyrate, we have 62.04g of carbon (C), 10.41g of hydrogen (H), and 27.55g of oxygen (O).

Step 2: Determine the ratio of each element.
To do this, divide each element's grams by its molar mass. The molar mass for carbon (C) is 12 g/mol, for hydrogen (H) it's 1 g/mol, and for oxygen (O) it's 16 g/mol.

So, the ratio for carbon (C) would be 62.04g / 12 g/mol, which equals 5.17.
The ratio for hydrogen (H) would be 10.41g / 1 g/mol, which also equals 10.41.
The ratio for oxygen (O) would be 27.55g / 16 g/mol, which equals 1.72.

Step 3: Simplify the ratios.
To simplify the ratios, we need to find the smallest whole number ratio. By dividing these ratios by the smallest ratio (which is 1.72), we get:
For carbon (C): 5.17 / 1.72 = 3
For hydrogen (H): 10.41 / 1.72 ≈ 6
For oxygen (O): 1.72 / 1.72 = 1

Therefore, the empirical formula for ethyl butyrate (pineapple oil) is C3H6O. And remember, even though it's called pineapple oil, you won't find it on the shelves next to the motor oil! It's used as an ingredient in fragrance and flavoring products.

To calculate the empirical formula for a compound, you need to determine the relative number of atoms of each element in the compound. Here are the steps to calculate the empirical formula for ethyl butyrate:

Step 1: Convert the percentages to grams.
- Assume you have 100g of the compound.
- From the given percentages, you can determine the mass of each element.

Mass of carbon (C) = 62.04% of 100g = 62.04g
Mass of hydrogen (H) = 10.41% of 100g = 10.41g
Mass of oxygen (O) = 27.55% of 100g = 27.55g

Step 2: Calculate the moles of each element.
- Use the atomic masses of carbon, hydrogen, and oxygen to determine the moles.

Molar mass of carbon (C) = 12.01 g/mol
Molar mass of hydrogen (H) = 1.01 g/mol
Molar mass of oxygen (O) = 16.00 g/mol

Moles of carbon (C) = Mass of carbon (62.04g) / Molar mass of carbon (12.01 g/mol)
Moles of hydrogen (H) = Mass of hydrogen (10.41g) / Molar mass of hydrogen (1.01 g/mol)
Moles of oxygen (O) = Mass of oxygen (27.55g) / Molar mass of oxygen (16.00 g/mol)

Step 3: Find the simplest whole number ratio.
- Divide the moles of each element by the smallest mole value obtained.

Divide the moles of carbon, hydrogen, and oxygen by the smallest mole value:
Moles of carbon (C) = Moles of carbon / Moles of the smallest value obtained
Moles of hydrogen (H) = Moles of hydrogen / Moles of the smallest value obtained
Moles of oxygen (O) = Moles of oxygen / Moles of the smallest value obtained

Step 4: Round the resulting ratios to the nearest whole number.
- The resulting ratios are the subscripts in the empirical formula.

The resulting whole number ratios will give you the empirical formula for the compound.
