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 a substance that contains 0.117 of carbon 0.233 of hydrogen and 0.117 of oxygen?
The molar ratios of carbon, hydrogen, and oxygen atoms are 1:2:1, so the empirical formula is CH₂O.
Combustion analysis of toluene a common organic solvent gives 5.86 mg of CO2 and 1.37 mg of H2O If the compound contains only carbon and hydrogen what is its empirical formula?
To find the empirical formula, we first need to convert the mass of CO2 and H2O to moles. From the molar ratios in the products, we find the moles of carbon and hydrogen present. Then, we determine the ratio of carbon to hydrogen atoms, giving the empirical formula as C7H8.
Is NH3 an empirical formula?
Yes, NH3 is an empirical formula. An empirical formula represents the simplest whole-number ratio of atoms in a compound. In the case of ammonia (NH3), the ratio of nitrogen to hydrogen is 1:3, making NH3 the empirical formula.
What is the empirical formula for water?
The empirical formula for water is H2O, indicating that each molecule of water contains 2 hydrogen atoms and 1 oxygen atom.
What is the empirical formula of 22 percent Carbon 4.6 percent Hydrogen 73.4 percent Bromine?
The empirical formula of the compound with 22% Carbon, 4.6% Hydrogen, and 73.4% Bromine is CHBr3, which represents one carbon atom, one hydrogen atom, and three bromine atoms in the simplest whole-number ratio.
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 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.
What contain carbohydrate?
Empirical formula. CH2O Carbon, hydrogen and oxygen.
What is the empirical formula of a substance that contains 0.117 of carbon 0.233 of hydrogen and 0.117 of oxygen?
The molar ratios of carbon, hydrogen, and oxygen atoms are 1:2:1, so the empirical formula is CH₂O.
What is the empirical number for water?
The empirical formula for water is H2O, indicating that water is composed of two hydrogen atoms for every oxygen atom.
Combustion analysis of toluene a common organic solvent gives 5.86 mg of CO2 and 1.37 mg of H2O If the compound contains only carbon and hydrogen what is its empirical formula?
To find the empirical formula, we first need to convert the mass of CO2 and H2O to moles. From the molar ratios in the products, we find the moles of carbon and hydrogen present. Then, we determine the ratio of carbon to hydrogen atoms, giving the empirical formula as C7H8.

What is the empirical formula of silicon hydride?
The empirical formula of silicon hydride is SiH4. This formula represents the simplest whole number ratio of silicon to hydrogen atoms in the compound.
What is the empirical formula for water?
The empirical formula for water is H2O, indicating that each molecule of water contains 2 hydrogen atoms and 1 oxygen atom.
What is the empirical formula for C3H5?
The empirical formula for C3H5 is C3H5 since it represents the simplest whole-number ratio of carbon to hydrogen atoms in the compound.
What is the empirical formula of 22 percent Carbon 4.6 percent Hydrogen 73.4 percent Bromine?
The empirical formula of the compound with 22% Carbon, 4.6% Hydrogen, and 73.4% Bromine is CHBr3, which represents one carbon atom, one hydrogen atom, and three bromine atoms in the simplest whole-number ratio.
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.
