L = an integer from 0 to n-1
<span>mL = an integer from -L to +L </span>
<span>ms = + or - 1/2 </span>
<span>the format is (n, L, mL, ms) </span>
<span>so your </span>
<span>n = 3... this is OK </span>
<span>L = 2.. also OK.. if n=3, L can = 0, 1, or 2 </span>
<span>mL = -3 is NOT ok... if L=2.. mL can only be -2, -1, 0, +1, or +2 </span>
<span>ms = +1/2 and that is ok
Hope this helps!</span>
Answer:
Nitrogen = 0.3 atm
Oxygen = 0.25 atm
Argon = 0.45 atm
Explanation:
According to Dalton's law of partial pressure, the total pressure in the container is equal to sum of the partial pressures of the individual gases.
Given;
Total pressure of the gases, P_total = 1 atm
Pressure of nitrogen, P_nitrogen = 0.3 atm
Pressure of oxygen, P_oxygen = 0.25 atm
Pressure of argon, P_argon = ?

Therefore, the contribution of each gas to the total pressure of the gas mixture is;
Nitrogen = 0.3 atm
Oxygen = 0.25 atm
Argon = 0.45 atm
It's in the periodic table.
See the attached picture. The number below 'Zn' is the molar mass. The closest answer choice is 65.38
To determine the number of moles(n) of a substance, divide its amount given in grams by the molar mass. The element in the problem is gold (Au) which has a molar mass of 196.97 grams per mole. The division is better illustrated below
n = 35.12 g / 196.97 grams per mole
The answer to the operation above is 0.1783 moles. Therefore, there are approximately 0.1783 moles of Au in 35.12 grams.
