A cylinder contains 3.1 L of oxygen at 300 K and 2.7 atm. The gas is heated, causing a piston in the cylinder to move outward. T
zubka84 [21]

Answer: The moles of gas present in the cylinder is 0.34 moles.

Explanation:

Given: P_{1} = 2.7 atm,   V_{1} = 3.1 L,     T_{1} = 300 K

P_{2} = ?,      V_{2} = 9.4 L,       T_{2} = 610 K

Formula used to calculate the final temperature is as follows.

\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}

Substitute the values into above formula as follows.

\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{2.7 atm \times 3.1 L}{300 K} = \frac{P_{2} \times 9.4 L}{610 K}\\P_{2} = \frac{5105.7}{2820} atm\\= 1.81 atm

Now, moles present upon heating the cylinder are as follows.

P_{2}V_{2} = n_{2}RT_{2}\\1.81 atm \times 9.4 L = n_{2} \times 0.0821 L atm/mol K \times 610 K\\n_{2} = \frac{17.014}{50.081} mol\\= 0.34 mol

Thus, we can conclude that moles of gas present in the cylinder is 0.34 moles.

NARA [144]
  • Answer:

<em> $ 434.40</em>

  • Explanation:

<em>41 miles ............ 1 gallon</em>

<em>4700 miles .......x gallon</em>

<em>x = 4700×1/41 = 114.63 gallons</em>

<em />

<em>114.63 gallons×$3.79 ≈  $ 434.40</em>

If an atom has an electron in the n = 4 state with ml = 2, what are the possible values of l?
Pavel [41]

Answer:

The possible values of l are 2 and 3

Explanation:

Each electrons have four quantum numbers:

  • n: the principal quantum number, which value matches with the energy level of the electron.
  • l: the secondary quantum number, which value can be from 0 to n-1
  • m: the magnetic number, which value can be from -l to l
  • sp: the spin number which value can be -1/2 or +1/2

In this case, n=4 so the values of l are:

l=0, 1, 2, 3

Now, if:

  • l=0 the value of m is m=0
  • l=1 the values of m are m= -1, 0, 1
  • l=2 the values of m are m= -2, -1, 0, 1, 2
  • l=3 the values of m are m= -3, -2, -1, 0, 1, 2, 3

Being all that said, l can be either  equal to 2 or 3
