when 0.1156 g of an unknown compound that contains carbon, hydrogen and nitrogen, is reacted with oxygen, 0.1638 g of co2 and 0.1676 g of h2o are collected. determine the empirical formula of this compound.

Respuesta :

CH 20 the empirical formula of this compound.

What do you mean by Empirical formula ?

The simplest whole-number ratio of the various atoms in a compound is represented by an empirical formula. The precise number of various atom types present in a compound's molecule is indicated by the molecular formula. The empirical formula for acetylene is CH. The empirical formula for acetylene is C2H2.

The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry. Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea.

Calculation with Explanation :

Along with the molar masses, into an equation to represent this. The subscript adjacent to the Os is unknown to us, but we do know that it is interacting with oxygen. We can determine what the byproducts of R C 2 and H 20 are. C. 2 and H. 20 are the amounts that have been provided. That was created. The coefficients in front of each one can be used to calculate how much of each is created. First, we're going to make them into moles.

By comparing the two, we may determine whether we require coefficients in front of them. We can determine the subscript that must be on the left side for them to balance. Starting with the carbon dioxide will be our first step. The 44g will go on the bottom, followed by the mole of CO 2 on top. To find the answer, divide this by 44 and multiply by 1.581. The method for H20 must be followed in the same manner, and the result should be approximately 0.0 358 Mole CO2. We shall begin with 0 6474 g and 18 g every additional .

In addition, this is 0.0359 moles, The c. 0., as we will discover. It was 2. That indicates that the ratio is 1-2. Both the one in front of us here and the one in front of them are creating the same number of moles. There is only one carbon because there are no coefficients up front. We can't see a subscript that says we have two hydrogens in the next line. I have two oxygens in total plus one more, and I have three oxygens to my right. Two of those oxygen tanks are here.

The easiest of the three is evaluating. The fact that they are smaller numbers and are the most straightforward makes sense. We observed the empirical formula above CH 20. In order to get the ratios between them, we first turned the number of grams into moles and then went backwards from there. We now know the molecule's empirical formula, which is CH 20.
