Answer:
0.86 g
Explanation:
Given:
Pressure = 725 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 725 / 760 atm = 0.9539 atm
Volume = 225 mL = 0.225 L (1 mL = 0.001 L)
Temperature = 25 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
0.9539 atm × 0.255 L = n × 0.0821 L.atm/K.mol × 298.15 K
⇒n = 0.0099 moles
From the reaction,
1 mole of chlorine is formed from 1 mole of
Thus, moles of = 0.0099 moles
Molar mass of = 86.9368 g/mol
Mass = Moles*Molar mass = 0.0099 moles * 86.9368 g/mol = 0.86 g

Explanation:
Hydrolysis is the chemical breakdown of a compound due to reaction with water. It may occur when acid or base is used as the catalyst.
The acid catalyzed hydrolysis of esters is the reverse of esterification. The alcohol and carboxylic acid that combined to form the ester are obtained in the process.
The acid catalyzed of butyl acetate is shown in the image attached.
