Using the ideal gas law, the estimated number of air molecules in a room that has a height of h = 3.38 m, a width of w = 7.8 m, and a length of L= 16.9 mis NV= 3.65 x 102/ molecules. The pressure in the room is the normal atmospheric pressure, P. = 1.013 x 10 Pa. The air temperature in the room in C. Use Avogadro's number, NA = 6.0 x 1023 molecules/mole). Please round your answer to one decimal place.Assume that you have helium gas in a container. The amount of helium in the container in moles is 1 = 22 moles. The gas is initially at T1 = 52 "C. How much energy, in Joules, must be added to the gas to increase its temperature to T2 = 166 C? Take the universal gas constant as 8.314 J/mol. K. Please round your answer to the nearest whole number (integer)
