There are then 1.07 grams of oxygen in the sample (1.07 + .13 + .8 = 2.0). Carbon has a molar mass of 6, oxygen is 8 and hydrogen is 1. This gives the molar ration of C:H:O at about 0.8/6:0.13/1:1.07/8, reduced to .13:.13:.13. Thus the empirical formula is CHO.

To find the empirical formula, we first need to calculate the moles of each element present. We find that there are 0.067 moles of carbon, 0.122 moles of hydrogen, and 0.014 moles of oxygen. Dividing these values by the smallest number of moles (0.014), we get a ratio of C₁H₉O₉, which simplifies to CH₆O₆. Therefore, the empirical formula of the sugar is CH₆O₆.

What is the empirical formula of the compound that is 75 carbon and 25 hydrogen?

The empirical formula of a compound is the simplest whole number ratio of the elements in the compound. In C75H25, the ratio of carbon to hydrogen is 75:25, which is equal to 3:1. Thus, the empirical formula is C3H.

Explain Why is H2O2 is not the empirical formula of hydrogen peroxide?

An empirical formula is the lowest ratio of elements in a compound. So since H2O2 can be reduced to HO (H1O1), that is the empirical formula. The molecular formula is H2O2.

What is the empirical formula of C4H6?

The empirical formula of organic compounds is the lowest whole number ratio of atoms contained in the substance, as defined in chemistry. The empirical formula gives the minimal ratio of the number of various atoms that exist. It's an empirical formula, if the formula is shortened, but not the exact number of atoms in the molecule, C4H6 is the chemical formula for butane. For every mole of carbon, there are two moles of hydrogen. The carbon-to-hydrogen ratio equals 2:3. C2H3 is the empirical formula for butane (C4H6). Hence, the correct answer is C2H3.
