Question

question 1-4 please :)

A sample of nitrogen gas is sealed into a 14.7L container at 426 torr and 106 2 °C How many nitrogen molecules are in the container? {Enter your value in E-notation with three significant figures.] QUESTION 2 A 567.6 ml sample of carbon dioxide gas, CO2, is collected at 1.41 atm and 22.3°C. What is the mass of the carbon dioxide? QUESTION 3 Automobile airbags use the decomposition of sodium azide, NaN3, to provide gas for rapid inflation 2 NaN3(s) - Na(s) + 3 N29). Using stoichiometry and the ideal gas law, calculate the mass (in g) of NaNg required to provide 303 L of N2(g) at 25 6 °C and 1.00 atm? QUESTION 4 Consider the reaction between hydrogen gas and oxygen gas to form water, 2 H2(g) + O2(g) + 2 H2O(g) How many grams of water could be produced by the reaction of 6.67 liters of hydrogen with 4 11 liters of oxygen at STP? (Hint check for limiting reagent)
