Answer:

C. Yes, if each sample contains 6.02 x 10²³ atoms.

Explanation:

It is possible for each sample to contain 1 mole of each sample if and only if each of the sample if made up of 6.02 x 10²³ atoms.

6.02 x 10²³ atoms is the Avogadro's number. This number is equivalent to a mole of a substance.

If the amount of matter in the given substance is at least one mole, it is possible that they are made up of one mole each of each substance.
If they contain lesser amount of atoms, then it is not up to one mole of substance.
But if it is greater, then, we can have even more than one mole of substance.

A mole is simply a unit of measurement and it is equivalent to 6.02 x 10²³ atoms.

A container is filled with a mixture of gases:

strojnjashka [21]

Answer:

The partial pressure of chlorine gas in the mixture is 1.55 atm.

Explanation:

Partial pressure of oxygen gas = $p_1=1.0 atm$

Partial pressure of nitrogen gas = $p_2=0.75 atm$

Partial pressure of chlorine gas = $p_3=?$

Total pressure of the mixture of gases = P = 3.30 atm

Using Dalton's law of partial pressure:

$P=p_1+p_2+p_3$

$3.30 atm=1.0 atm+ 0.75 atm+p_3$

$p_3=3.30atm - (1.0 atm+ 0.75 atm)=1.55 atm$

The partial pressure of chlorine gas in the mixture is 1.55 atm.

<h3>What is colligative property?</h3>

Colligative properties in chemistry are those of a solution that depend on the amount of solute particles to solvent particles in a solution rather than the makeup of the individual particles.
The number ratio can be connected to the several units used to measure a solution's concentration, including molarity, molality, normalcy (chemistry), etc.
For ideal solutions, which are ones that have thermodynamic properties similar to those of an ideal gas, and for diluted actual solutions, the assumption that solution properties are independent of the type of solute particles is exact.

<h3>What factors affect colligative properties?</h3>

A property of a solution is said to be collative if it depends simply on the proportion of solute to solvent particles in the solution and not on the nature of the solute.
