How many moles are contained in 6.55 x 10^23 formula units of KNO3?

1.09 moles

Explanation:

There are 6.02 x 10²³ formula units in one mole

=> 6.55 x 10²³ formula units/6.02 x 10²³formula units/mole = 1.09 moles.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
