missions | 1 Attempt Remaining Nitrate salts (NO 3 ), when heated, can produce nitrites (NO2) plus oxygen (O2). A sample of potassium nitrate is heated, and the O2 gas produced is collected in a 710 ml flask. The pressure of the gas in the flask is 2.6 atm, and the temperature is recorded to be 331 K. The value of R= 0.0821 atm (mol K) How many moles of O2 gas were produced? moles After a few hours, the...
1.) Use the ideal gas law to calculate the volume occupied by 0.500 mol of nitrogen gas at 1.60 atm pressure and at 27°C. R = 0.0821 L*atm/(K*mol). 0.694 L 7.10 L 7.70 L 7.89 L (separate question) 2.What will be the final gas temperature in kelvins?
1)What is the molar mass of a gas if 1.07 grams of the gas in a 0.539 L flask at 296 K has a pressure of 1.275 atm? Use R = 0.08206 Latm/molK 2)A 8.7 L cylinder contains a sample of gas at 15.7 atm. What pressure would the gas be in a 6.7 L cylinder at this same temperature? Report your answer in atmospheres to the correct number of significant figures.
What will be the pressure of 1.50 mol of an ideal gas at a temperature of 20.5 °C and a volume of 62.7 L? Use R = 0.0821 atm • L/mol • K. atm ?
What will be the pressure of 2.00 mol of an ideal gas at a temperature of 30.5 °C and a volume of 62.1 L? Use R = 0.0821 atm • L/mol • K. 2.20 atm
Please help with these two 1. A flask is filled with 1.08 moles of a gas at 20.7 K and 646.8 mm Hg. The flask is then opened and an additional 1.33 moles are added. The temperature of the flask is then changed to 272.4 K. What is the pressure (in atm) of the flask under these final conditions? 2. The density of a gas is 4.22 g/L at a pressure of 1.77 atm and a temperature of 14.66 °C. What...
