The simplest formula of the alcohol is,

Explanation:

The chemical equation for the combustion of hydrocarbon having carbon, hydrogen and oxygen follows:

where, 'x', 'y' and 'z' are the subscripts of Carbon, hydrogen and oxygen respectively.

We are given:

Mass of

Mass of

We know that:

Molar mass of carbon dioxide = 44 g/mol

Molar mass of water = 18 g/mol

For calculating the mass of carbon:

In 44 g of carbon dioxide, 12 g of carbon is contained.

So, in 1.913 g of carbon dioxide,  of carbon will be contained.

For calculating the mass of hydrogen:

In 18 g of water, 2 g of hydrogen is contained.

So, in 1.174 g of water,  of hydrogen will be contained.

Mass of oxygen in the compound = (1.000) - (0.522 + 0.130) = 0.348 g

To formulate the empirical formula, we need to follow some steps:

Step 1: Converting the given masses into moles.

Moles of Carbon =

Moles of Hydrogen =

Moles of Oxygen =

Step 2: Calculating the mole ratio of the given elements.

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.022 moles.

For Carbon =

For Hydrogen  =

For Oxygen  =

Step 3: Taking the mole ratio as their subscripts.

The ratio of C : H : O = 2 : 6 : 1

The empirical formula for the given compound is

Therefore, the simplest formula of the alcohol is,

1. Politics is the way that people living in groups make decisions. Politics is about making agreements between people so that they can live together in groups such as tribes, cities, or countries. ... These people are called politicians. Politicians, and sometimes other people, may get together to form a government.

2. Politics (from Greek: Πολιτικά, politiká, 'affairs of the cities') is the set of activities that are associated with making decisions in groups, or other forms of power relations between individuals, such as the distribution of resources or status. The academic study of politics is referred to as political science.
