Question

How many molecules does 46g ethyl alcohol contain

Answer 1

Answer:

Explanation:

It is very simple to know that how many number of molecules with 46 gram of ethyl alcohol contain

Ethyl alcohol is also known as ethanol

Molecular formula of Ethanol is

CH3-CH2-OH or C2H5OH

2 C atoms = 24 u

6 H atoms = 6 u

1 O atoms = 16 u

Total molecular mass of ethyl alcohol is = 46 grams

Therefore one mole of ethyl alcohol is 46 grams

Thus by using the Avogadro number we can know the number of the molecules 46 grams of ethyl alcohol contains

Number of molecules is equals to Avogadro number X number of moles

= 6.022 x 10²³ X 1

= 6.022 x 10²³ molecules...

Thus, 46 grams of ethyl alcohol contain 6.022 x 10²³ molecules.....
