At 4.00 L, an expandable vessel contains 0.864 mol of oxygen gas. How many liters of oxygen gas must be added at constant temperature and pressure if you need a total of 1.36 mol of oxygen gas in the vessel? Express the volume to three significant figures, and include the appropriate units.

Expert Solution

from Avogadro's law

at constant temperature and pressure equal volume of all gases contains equal no of moles.

Vn

V = Kn

V1/V2 = n1/n2

Inital final

V1 = 4L V2 =

n1 = 0.864moles n2 = 1.36moles

V1/v2 = n1/n2

V2 = V1n2/n1

= 4*1.36/0.864 = 6.29L >>>>answer
