Answer:
The answer to your question is: 5 friends
Explanation:
Data
Larry bought 12 1/2 pounds of candy
gave each friend 2 1/2 pounds
number of friends = ?
Process
Convert mixed fractions into improper fractions
12 1/2 = (24 + 1) / 2 = 25 /2
2 1/2 = (4 + 1) / 2 = 5/2
Divide the fractions

= 
= 5

Answer:
85.5 mmHg is the pressure of the gas sample when the valve is opened.
Explanation:
The combined gas equation is,

where,
= initial pressure of gas in container A = 165 mmHg
= final pressure of gas = ?
= initial volume of gas in container A= 
= final volume of gas = 135 mL + 117 mL = 252 mL
= initial temperature of gas in container A = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:



85.5 mmHg is the pressure of the gas sample when the valve is opened.
