A sample of a gas exerts a pressure of 8.2 atm when confined in a 2.93 dm³ container at 20°C. The number of moles of gas in the sample is?

(R = 0.082 litre atm / deg mole)

yea
pv=nRT
make n the subject formula
n= PV/RT
n= 8.2×293/0.082×293
n=2402.6/24.026
n=1

PV = nRT
2.93 x 8.2 = 0.082 x 293 xn
∴ n = (2.93 x8.2) / (0.082 x 293)
n = 1
This is the right answer
