Answer:
2.26 × 10²⁴ atoms of Fe
Explanation:
To calculate the amount of atoms of a substance using the amount of moles, we must multiply by Avagadro's number.
(3.75mol) × (6.02 × 10²³) = 2.26 × 10²⁴ atoms of Fe
According to the law of conservation of Mass:
In a chemical reaction mass can neither be created nor be destroyed
So, we can say that: Mass of A + Mass of B = Mass of C
In the given reaction,
One of the reactants weigh 5 grams and another one weighs x grams
The mass of the product of this reaction is 9 grams
<u>Mass of reactant B:</u>
Mass of A + Mass of B = Mass of C
5 + x = 9
x = 4 grams
