Using equation e=(hcrh)(1n2)=(−2.18×10−18j)(1n2), calculate the energy of an electron in the hydrogen atom when n= 5.

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?
