Question

calculate the number of moles and molecules of acetic acid present in 22g of it​

Answer 1

Answer:

The moles and molecules of acetic acid present in 22g can be calculated very easily by performing following steps .

Step 1.

Molecular Formula of Acetic Acid = CH3COOH

Step 2:

Add all the mass of the molecular formula,

C= 12

H=1

O= 16

Therefore, CH3COOH = 12+(1*3)+12+16+16+1

                                      = 60

Step 3 :

Mole = Molar Mass / Given Mass

      = 60/22

      = 2

Step 4 :

Number of molecules = No of mole * 6.023 * 10^ 23

                                     =  2 * 6.023 * 10^ 23

                                      = 12.046 * 10^23(Answer)
