Answer: 0.52 L of 15 M will be used to prepare this amount of 0.52 M base.
Explanation:
But on diluting the number of moles remain same and thus we can use molarity equation.
(to be prepared)
where,
=concentration of stock solution = 15 M
= volume of stock solution = ?
= concentration of solution to be prepared = 0.52 M
= volume of solution to be prepared = 15 L
Thus 0.52 L of 15 M will be used to prepare this amount of 0.52 M base
Answer: The work done for the given process is -2188.7 J
Explanation:
To calculate the amount of work done for an isothermal process is given by the equation:
W = amount of work done = ?
P = pressure = 50.0 atm
= initial volume = 542 L
= final volume = 974 L
Putting values in above equation, we get:
To convert this into joules, we use the conversion factor:
So,
The negative sign indicates the system is doing work.
Hence, the work done for the given process is -2188.7 J
