How many moles of rice grains are equal to 1.807 x 10^24 grains of rice WITH SOLUTION PO SANA.. ​

In this problem,it is very important to use the constant called Avogradro's number which is equal to 6.022 * 10^23 particles per mole. For any kind of substance, whatever it is, this is the number of particles that constitute 1 mole.

This means that 6.022x10^23 grains is equivalent to 1 mole of rice grain.

1.807*10^24 grains (1 mole/ 6.022*10^23) = 3 moles of rice grains

Explanation:

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
