If 10.0 liters of oxygen at STP are heated to 785.15 °K, what will be the new volume of gas if the pressure is also increased to 102.6 Kpa of pressure?

The new volume of gas is 28.5 L

Explanation:

The combined gas equation is,

where,

= initial pressure of gas = 1.00 atm (at STP)

= final pressure of gas = 102.6 kPa = 1.01 atm    (1 kPa= 0.0098 atm)

= initial volume of gas = 10.0 L

= final volume of gas = ?

= initial temperature of gas =  (STP)

= final temperature of gas =

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

The new volume of gas is 28.5 L

a electronegativity decreases beacuse the size of nucleus is bigger.
