Question

Two closed vessels contain chlorine gas at the same conditions of temperature and
pressure, so if the first vessel whose volume = 1.3 L contains 6.7 mol of gas,
what is the number of moles in the second vessel whose volume = 2.33 L ? .............​

Answer 1

Answer:12 mol

Explanation: both vessels are at the same temp and pressure (and the pressure is low and/or the temperature high).

6.7mol per 1.3L = 6.7/1.3 mol/L

so in 2.33L = 6.7*2.33/1.3 = 12 mol
