Find the empirical formula of the following compounds:<br> (c) A hydrocarbon with 79.9 mass % carbon
rodikova [14]

The compound is 82.76% C and 17.24% H

In chemistry, the empirical formula of a chemical compound is the simplest whole number ratio of atoms present in a compound.

<h3>Describe the empirical formula.</h3>

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.

The simplest whole number ratio of each type of atom in a compound is its empirical formula. It can be determined from data on the mass of each component in a compound or from the composition's proportion.

How many plutonium atoms are present in 6.1 moles of plutonium metal? Give your answer in scientific notation. Enter your answer
Irina-Kira [14]

<u>Answer:</u> The number of atoms of plutonium present in given number of moles are 3.7\times 10^{24}

<u>Explanation:</u>

We are given:

Number of moles of plutonium metal = 6.1 moles

According to mole concept:

1 mole of an element contains 6.022\times 10^{23} number of atoms.

So, 6.1 moles of plutonium will contain = 6.1\times 6.022\times 10^{23}=3.7\times 10^{24} number of plutonium atoms.

Hence, the number of atoms of plutonium present in given number of moles are 3.7\times 10^{24}
