Response:
V1 = 20.3L
Clarification:
P2 = 811.4Pa
V2 = 25.6L
P1 = 1023.6Pa
V1 =?
To answer this query, we will utilize Boyle's law, which states that the volume of a gas at constant temperature is inversely related to its pressure.
In mathematical terms,
V = k / P, where k = PV
The relationship can be defined as P1 × V1 = P2 × V2 = P3 × V3 =......=Pn × Vn
This simplifies to P1 × V1 = P2 × V2
Let’s rearrange for V1
V1 = (P2 × V2) / P1
Substituting values gives
V1 = (811.4 × 25.6) / 1023.6Pa
So, V1 = 20771.84 / 1023.6
This results in V1 = 20.29L, rounded to 20.3L
Solution:
Molality measures the concentration of a solute in a solution, defined by the amount of solute per specific mass of solvent.
Thus,
Molality = moles of solute / kg of solvent.
Therefore, kg of solvent = moles of solute / molality.
moles of solute = mass / molar mass
= 25.31 g / 101.1 g/mole
= 0.2503 mole.
kg of solvent = 0.2503 mole / 0.1982 m
= 1.263 kg
= 1263 g.
This is the final answer.
One electron is involved. Explanation: In redox reactions, determining the equivalents requires knowledge of the number of transferred electrons. In this specific case, one equivalent corresponds to a transfer of a single electron.
