A 18.0 L gas cylinder is filed with 6.20 moles of gas. The tank is stored at 15 °C. What is the pressure in the tank? Express your answer to three significant figures and include the appropriate units. View Available Hints) PÅ OG ? PV = nRT The variable is known as the universal gas constant and has the value R=0.0821 Latm/(mole-K). The units of R dictate the units for all other quantos so when using this value of Ruse units of atmospheres for pressure, there for volume, and is for temperature P- Value Units Submit Part A 200. Lin is used for vitiling comics, it is currently operating at 125 C, and the pressure is 1050 amHow many moles of molecules are within the centre of the kin? and include the

Answer 1

Use ideal gas law

PV = nRT

P = nRT / V

= 6.20*0.082*(273.15+15)(in Kelvin) / 18.0

= 8.14 atm
