To convert C into K, add 273. Plug into the ideal gas law and solve for moles of water. convert moles of water into grams of water

Like so? m = PVM / RT R = (1atm x 22.4L) / (1mole x 273K) = 0.0821Latm/moleK T = 26 + 273 = 299K m = 0.98atm x 10.2L x 18g/mole / (0.0821Latm/molek x 299K) = 7.33gH2O

i get about 7.5g, but that's close enough, given differences in rounding
