What is the pressure in a 5.00 L tank with 49.00 grams of oxygen gas at 350 K? ___atm
ziro4ka [17]

Answer:

The right answer is "8.81 atm".

Explanation:

Given:

V = 5.00 L

Mass = 4900 g

MW = 32 g/mol

T = 350 K

Now,

Number of moles will be:

n = \frac{Mass}{MW}

   =\frac{49.00}{32}

   =1.53125 \ mole

By using the ideal gas equation, we get

⇒ PV=nRT

or,

⇒    P=\frac{nRT}{V}

By substituting the values, we get

           =\frac{1.53125\times 0.0821\times 350}{5.00}

           =\frac{44.1}{5.00}

           =8.81 \ atm

Observe: Select the ELECTRON CONFIGURATION tab. Make sure the subshells are ordered by Energy, which will arrange them from lowe
Mrrafil [7]

Answer:

The order in which the orbitals is filled is 1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p

Explanation:

S orbitals each hold two electrons, p orbitals hold 6, d orbitals hold 10, and f orbitals hold 14. 1s has the least energy and 7 p has the greatest energy, so the order in which they are filled is listed above.
