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,

For CH4, you have a total of 8 total valence electrons. Drawing the Lewis structure for CH4 (named methane) requires only single bonds. It's one of the easier Lewis structure to draw.

Hello!

How many moles of phosphoric acid are there in 658 grams of phosphoric acid ?

We have the following data:

Molar Mass of phosphoric acid (H3PO4)

H = 3*(1u) = 3 u

P = 1*(30.97u) = 30.97 u

O = 4*(16u) = 64 u

------------------------------------

Molar Mass of phosphoric acid (H3PO4) = 3 + 30.97 + 64

Molar Mass of phosphoric acid (H3PO4) = 97.97 (≈ 98 g/mol)

Now, let's make the rule three, grams relative to the mole (g/mol), let's see:

98 g ---------------- 1 mol

658 g -------------  y mol

Product of extremes equals product of means
