Answer:
The concentration of NaCl = 0.3374 M
Explanation:
Given :
Molarity of AgNO₃ = 0.2503 M
Volume of AgNO₃ = 20.22 mL
The conversion of mL into L is shown below:
Thus, volume of the solution = 20.22×10⁻³ L
Molarity of a solution is the number of moles of solute present in 1 L of the solution.
The formula can be written for the calculation of moles as:
Thus,
The chemical reaction taking place:
According to reaction stoichiometry:
<u>1 mole</u> of AgNO₃ reacts with <u>1 mole</u> of NaCl
Thus,
5.0611×10⁻³ moles of AgNO₃ reacts with 5.0611×10⁻³ moles of NaCl
Thus, moles of NaCl required = 5.0611×10⁻³ moles
Volume of NaCl required = 15.00 mL
The conversion of mL into L is shown below:
Thus, volume of the solution = 15.00×10⁻³ L
Applying in the formula of molarity as:
<u>Thus, the concentration of NaCl = 0.3374 M</u>
<u> There are more total ions in 2.2 moles of </u>
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions.
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms.
Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.
