Molarity is the estimation of the solute concentration in the solution. The final molar concentration of the acetate anion in the solution is 0.006 M.
<h3>What is Molarity?</h3>
Molarity is the ratio of the moles to the volume in liters.
Given,
Mass of lead (II) acetate = 0.258 gm
Volume of solution = 0.25 L
Moles are calculated as:
Moles = mass ÷ molar mass
= 0.258 g ÷ 325.29 g/mol
= 0.00079
Molarity is calculated as:
M = moles ÷ volume
= 0.00079 ÷ 0.25
= 0.0032
The molar concentration of the acetate ions: 2 × 0.0032 = 0.0064 M
Therefore, the molarity of the acetate anion in the solution is 0.006 M.

Answer: Option (4) is the correct answer.
Explanation:
Activation energy is the minimum amount of energy required by the reactants to participate in the chemical reaction.
Therefore, reactant molecules whose energy is less than the activation energy are not able to participate in the reaction. Hence, a catalyst lowers the activation energy so that molecules with less energy can also participate in the reaction.
Thus, a catalyst is a specie that increases the reaction rate and has a lower activation energy.
Answer:
1 L
Explanation:
ppm means parts per million. Generally the relationship between mass and litre is given as;
1 ppm = 1 mg/L
This means that 1 ppm is equivalent to 1 mg of a substance dissolved in 1 L of water.
Answer:The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.
