1. In each of the following series, indicate which element coes belong to the same group as the other two:

0.185 L

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 = 0.98 atm

= final pressure of gas = 1 atm  (at STP)

= initial volume of gas = 0.165 L

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =  (at STP)

Now put all the given values in the above equation, we get:

Thus the volume of this gas at STP be 0.185 L
