How many moles do 9.12x10^25 formula units of kcl represent

151.4 moles

Explanation:

Data Given:

Formula units of KCl = 9.12x10²⁵

no. of moles = ?

Solution

Formula used

             no. of moles = no. of particles / Avogadro's number

Where

Avogadro's number = 6.022 x 10²³

Put values in above equation

  no. of moles = 9.12x10²⁵ formula units / 6.022 x 10²³ (formula units/mol)

  no. of moles =  151.4 moles

So,

There are 151.4 moles is represent by 9.12x10²⁵ of KCl formula units

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

increased stability in the completion of fluorine's outer shell.
