Question

Question 9 x Incorrect. Check that your units for each given in the problem match the units of the gas constant (R) from the ideal gas law. A 21.3 L cylinder contains nitrogen gas at 11.6 °C and 747 torr. How many moles of nitrogen are in the cylinder? 0.0764 Moles of nitrogen = the tolerance is +/-2% SHOW HINT LINK TO TEXT By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor.

Answer 1

solution 0.8956 mole of nitrogen of nitrogen in the cylinder Explaination Formula used from ideal laue gas pu= nRT 0 n = Ру RT where na 00: of males of in sample P= Pressure of gas v = volume of gas. Temperature of gas gas constant R= Universal R = 0.0821 atmL molk In given question v= 21.3 L T= 11.6°C (27. 15 +1.6 k T= 284,75K CS Scanned with CamScanner

P= my 47 forr Convert torr into atom 0.00132 atm I toor 947 torr = 0.983 atm P=0.gazatm atm L 0.0821 R= molk Putting aboue values in equation = 0.983 atm X 2113 K 0:0821 atm K X 284.75 K moly mole n = 20.9379 23.377975 n=0.8956 mole mole in the So 0.8956 mole of nitrogen Cylinder CS Scanned with CamScanner
