You should solve like this.
Answer:
The percent yield is 42.52%.
Explanation:
Theoretical yield of beryllium chloride = 12.7 g
Actual yield of the beryllium chloride = 5.4 g
The formula used for the percent yield will be :
Now put all the given values in this formula, we get:
The percent yield is 42.52%.
Answer: 2232 torr
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 750 torr
= final pressure of gas = ?
= initial volume of gas = 36.0 L
= final volume of gas = 15.0 L
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The pressure will be 2232 torr if the volume changes to 15.0 L and the temperature changes to 78 °C, if the amount of gas stays the same.
