change temps to Kelvins
P2V2/T2=P1V1/T1
a) solve for V2
b. pv=nRT change V to m^3 (22.4E-3)
R=PV/nT=101325*22.4E-3/(1*273)=...
c. PV=nRT
n=PV/RT
At a temperature of 18.0°C of 23.0cm^3 of a certain gas occupies has pressure of 103 kPa.
(a) What volume would the gas occupy at a temperature of 0.00°C and pressure of 101kPa?
(b) 1.00 moles of a certain gas occupies a volume of 22.4 litres at 0.00°C and 101325 Pa. Show that the gas constant R = 8.31 J K^-1 mol^-1.
(c) Determine the number of moles of gas in the 23.0cm^3 sample above.
