Enough nitrogen must be generated in the bag to create a total pressure of 3.00 atm, which then drops as the bag slowly deflates. Assuming the volume of the bag is 51.0 L and the temperature in the car is 24 °C, calculate the molar quantity of N2 that must be generated.What molar quantity of sodium azide is required to generate this much nitrogen?
What volume of 0.160 M of Li2S solution is required to completely react with 125 mL of 0.160 M of Co(NO3)2
A sample of neon gas used in a neon sign occupies a volume of 1.50 L at a pressure of 630 torr. Calculate the volume of the gas if the pressure in the glass tube of the sign is 793 torr.
Calculate the amount of heat liberated (in kJ) from 305 g of mercury when it cools from 82.0°C to 13.0°C.
The vapor pressure of pure acetone (propanone) is 266 torr. When a non-volatile solute is added, the vapor pressure of acetone above the solution falls to 232 torr. What is the mole fraction of the non-volatile solute in the solution?
