The volume of the stock solution needed is 213.88 mL to get new concentration.
<h3>What is molarity?</h3>
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution.
Determination of the volume of stock solution.
Volume of diluted solution (V₂) =550 mL
Molarity of diluted solution (M₂) =0.70 M
Molarity of stock solution (M₁) = 1.8 M
Volume of stock solution needed (V₁) =?
M₁V₁ = M₂V₂
1.8 M × V₁ = 0.70 M × 550 mL
V₁ = 213.88 mL
Thus, the volume of the stock solution needed is 213.88 mL.

Answer: An acid contains more hydrogen ions than hydroxide ions.
Explanation:
An acid is defined as the chemical compound which has a high concentration of hydrogen ions. They are considered as proton donors and they act as proton
donors when they have high concentration of hydrogen ions.
A base is defined as a chemical substance which has high concentration of hydroxide ions. They are considered as proton acceptors and they act as proton
acceptors when they have low concentration of hydrogen ions.
Hence, an acid is contains more hydrogen ions than hydroxide ions.
Amino acids is the answer
