Using the ideal gas law, estimate the approximate number of air molecules in a room that has a height of 2.0 m, a width of 6.2 m, and a length of 12.6 m. The air in the room is at a temperature of 22 C and under normal atmospheric pressure (i.e., 1.013 x 105 Pa). (Use Avogadro's number, NA = 6.0 x 10- molecules per mole. Also universal gas constant R = 8.314 J/mol. K). Please express your answer as a number with one decimal place multiplied by 1027. For example, if your answer is 5.7 x 1027, , put only 5.7 in the answer box.Assume that you have a container with 13? moles of helium gas at 28.? \"C. How much energy, in Joules, must he added to the gas to increase its temperature to 64.2 \"C? Take the universal gas constant as 8.314 meol. K. Please round your answer to the nearest whole number {integer}
