I have an unknown quantity of gas in 31.0 L at 260 mmHg and 87°C, how many moles of gas do I have A 1.48 moles
B 0.36 moles
C 22.4 moles
D. 273 moles

B. 0.36 moles

Explanation:

According to ideal gas equation:

P = pressure of gas = 260 mm Hg = 0.342 atm         (760 mm Hg= 1atm)

V = Volume of gas = 31.0 L

n = number of moles = ?

R = gas constant =

T =temperature =

Thus the moles of gas present are 0.36

is there multiple choice answers?
