A sample containing 7.60 gas has a volume of 31.0 . Pressure and temperature remain constant.What is the volume after 3.00 is added to the gas already in the container

are 7.60 and 3.00 in moles? if it is,
recall the formula relating moles (n) and volume (V), at a constant P and T:
n1 / V1 = n2 / V2
plug in the given values to the equation:
7.60 mol/ 31.0 = (7.60 + 3) mol / V2
then solve for V2.
hope this helps. :)

With no units this is not a problem but just gibberish.
