Of two samples of nitrogen gas, sample A contains 1.5 moles of nitrogen in a vessel of the volume of 37.6 dm3 at 298 K, and sample B is in a vessel of volume 16.5 dm3 at 298 K. Calculate the number of moles in sample B.

उत्तर
nA = 1.5 mol
nB = ?
VA = 37.6 dm3
VB = 16.5 dm3
(T = 298 K constant)
`"V"_"A"/"n"_"A" = "V"_"B"/"n"_"B"`
`37.6/1.5 = 16.5/"n"_"B"`
`25.06 = 16.5/"n"_"B"`
`"n"_"B" = 16.5/25.06`
`"n"_"B"` = 0.658 mol
∴ The number of moles in sample B is 0.658 mol
