Question

A container of hydrogen gas has a volume of 1.46 liters, a pressure of 2.18 atm, and a temperature of 185 Kelvin. How many moles of gas are in the container?

Answer 1

Here applying ideal gas equation
PV= NRT
put R =0.0821 Litre atm per kelvin per mol
2.18×1.46=n ×0.0821× 185
so n = no. of moles of gas=0.20955 moles (by calculating upper equation)
