It would be a solution because it dissolved in the water obviously turning it blue .water dissolves so many solutions that it is often called the "universal solvent".
The fact that you want to yes is funny
CO2 AND H2O e.g. C3H8+5O2=3CO2+H2O
From the ideal gas equation, we know that PV = nRT
where, P = pressure, V = volume occupied, n = number of moles of gas, R = universal gas constant=0.082L atm mol-1 K-1 and T = temperature.
Given: P = 2.8 atm, V = 98 l and T = 292 k.
Therefore n =
=
= 11.46
