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.
