Best ResponseYou've already chosen the best response.1To 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

Best ResponseYou've already chosen the best response.1Like 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
