Explanation:

Moles of nitrogen gas =

Moles of oxygen gas =

Mole fraction of nitrogen gas=

Mole fraction of oxygen gas=

Total  umber of moles in container :

n == 0.0428 mol + 0.0240 mol = 0.0668 mol

Volume of the container = V = 1.65 L

Temperature of the container = T = 15°C = 288.15 K

Total pressure in the container = P

Using an ideal gas equation:

P = 0.9577 atm

Partial pressure of nitrogen gas =

Partial pressure of nitrogen gas =

Partial pressure of nitrogen gas and oxygen gas can be calculated by using Dalton's law of partial pressure:

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
