How many moles are equal to 1.4 x 10^24 atoms of aluminum

Svetlanka [38]

Answer: 2.3 moles

Explanation:

Recall that based on Avogadro's law, 1 mole of any substance has 6.02 x 10^23 atoms

So if 1 mole of Aluminum = 6.02 x 10^23 atoms

Then, Z moles = 1.4 x 10^24 atoms

To get the value of Z, we cross multiply:

1 mole x 1.4 x 10^24 atoms = Z x (6.02 x 10^23 atoms)

1.4 x 10^24 atoms = Z x (6.02 x 10^23)

Hence, Z = (1.4 x 10^24 atoms) ➗ (6.02 x 10^23 atoms)

Z =2.3 moles

Thus, there are 2.3 moles in 1.4 x 10^24 atoms of aluminum.

3 moles of NaOH reacts with 1 mole of phosphoric acid.

<h3>What is the moles ratio of the NaOH and Phosphoric acid reaction?</h3>

The moles ratio of the reaction between NaOH and Phosphoric acid is given by the equation of the reaction below:

$3\:NaOH + H_{3}PO_{4} \rightarrow Na_{3}PO_{4} + 3\:H_{2}O \\$

Based on the equation of the reaction, 3 moles of NaOH reacts with 1 mole of phosphoric acid.
