4. Nitrogen gas is commonly sold in 49.0 L steal cylinders at a pressure of 150 atm.(a) How many moles of nitrogen are in the container if the temperature of the cylinder is 21°C.(b) How many moles of nitrogen will there be if the container above is heated to 100°C? (careful here)(c) What is the mass of nitrogen gas in the cylinder in part (a)?(d) What volume would the nitrogen occupy at 21°C, if the pressure was reduced to 1.02 atm?(e) What would be the pressure of the nitrogen gas in the cylinder when the temperature is raised to 39°C?
