Answer:- Van't hoff factor(i) for the unknown ionic compound is 2.77.

Solution:- Elevation in boiling point is a colligative property and the equation used for solving this type of problems is...

delta Tb = i x m x kb

where delt Tb is elevation in boiling point.

i is Von't hoff factor.

m is molality of the solution and kb is the molal elevation constant. It's value for water is 0.512.

Boiling point of solution is given as 103.4 degree C and we know that water boils at 100 degree C.

So, delta Tb = 103.4 - 100 = 3.4 degree C

molality is given as 2.4m.

Let's plug in the values...

3.4 = i x 2.4 x 0.512

i = 3.4/(2.4 x 0.512)

i = 2.77

<span>The molar volume of a gas at STP, in liters, is 22.4

you then multiply 22.4 by 2 to get the answer to the next question:
</span><span>
You can use the molar volume to convert 2 mol of any gas to 44.8 L
</span>
<span>You can also use the molar volume to convert 11.2 L of any gas to 0.500 mol.
</span>
Avogadro’s law tells you that 1.2 L of O2(g) and 1.2 L of NO2(g<span>) are the same </span><span>numbers of moles of gas.</span>

Identify the gas law that applies to the following scenario: A 36.5 liter balloon holding 2.9 moles of carbon dioxide leaks. If
jarptica [38.1K]

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are <u>inversely</u> related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are <u>proportional</u>. We see this in the formula \frac{V1}{T1} = \frac{V2}{T2}.

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are <u>proportional</u>. We see this in the formula \frac{P1}{T1} = \frac{P2}{T2}.

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula \frac{V1}{n1} = \frac{V2}{n2}.

Plugging in the values based on Avogadro's Law, we'll have:

\frac{36.5}{2.9} = \frac{V2}{1.2}

12.6 = \frac{V2}{1.2}

12.6 x 1.2 = V2

15.1L =V2
