Answer: The final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Explanation:
According to the dilution law,
where,
= molarity of stock
solution = 2.5 M
= volume of stock
solution = 5 ml
= molarity of diluted
solution = ?
= volume of diluted
solution = 750 ml
Putting in the values we get:
Therefore the final concentration when 5 ml of a 2.5M copper sulphate solution is diluted to 750 ml is 0.017 M
Answer : The pressure after the temperature change is, 0.752 atm
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
or,
where,
= initial pressure = 0.82 atm
= final pressure = ?
= initial temperature =
= final temperature =
Now put all the given values in the above equation, we get:
Thus, the pressure after the temperature change is, 0.752 atm
