The law which this student is thinking of is the law of conservation of mass (LOCOM).
<h3>What is LOCOM?</h3>
LOCOM is an abbreviation for the law of conservation of mass and it states that mass is neither created nor destroyed in any chemical reaction.
This ultimately implies that, the mass of any substance in a balanced chemical equation or chemical reaction would remain the same at the end.
According to the law of conservation of mass (LOCOM), the mass of all the reacting chemical elements of any substance must be equal (remain the same) to the mass of the product formed during a chemical reaction.

Moles of Sulfuric acid needed to react completely : 3.2
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction (balanced)
<em>H₂SO₄ (aq) + 2 LiOH (aq) ⇒ Li₂SO₄ (aq) + 2 H₂O (l)</em>
moles of LiOH = 6.4
From equation, mol ratio of H₂SO₄ : LiOH = 1 : 2, so mol H₂SO₄ :

<span>No, I believe this is not an example of a chemical reaction.
What we actually see here is a physical change of the solution. Since we are adding
more water to an aqueous solution which is also made up mostly of water, what
we are simply basically doing is dilution. Since the solution is being diluted,
so definitely the color turned lighter.</span>
A chemist must prepare 0.200 L of 1.00 M aqueous silver nitrate working solution. He'll do this by pouring out 1.82 mol/L aqueous silver nitrate stock solution into a graduated cylinder and diluting it with distilled water. How many mL of the silver nitrate stock solution should the chemist pour out?
Answer: 0.110 L
Explanation:
According to the dilution law,
where,
= molarity of stock silver nitrate solution = 1.82 M
= volume of stock silver nitrate solution = ?
= molarity of diluted silver nitrate solution = 1.00 M
= volume of diluted silver nitrate solution = 0.200 L
Putting in the values we get:
Therefore, volume of silver nitrate stock solution required is 0.110 L
Many organisms need clean drinking water and we also need moisture in the air for us to stay hydrated
