Answer:

151.4 moles

Step-by-step 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
