To prepare a lab solution a chemist dissolves solid potassium chloride in a given
Neporo4naja [7]

The solution could be described like a saturated and concentrated solution.

<h3>Solutions</h3>

Dissolution of solutions can occur in certain ways. These ways depend on the solvent dilution coefficient and the amount of solute.

If the amount of solute is less than the solvent can dissolve, the solution is unsaturated.

If the amount of solute is exactly the same, the solution is saturated.

If the amount is greater, the solution is supersaturated.

So, since the amount of solute is exactly equal to the amount that the solvent can dissolve, the solution is saturated and concentrated.

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.
