At 20oC, a 2.32 M aqueous solution of Ammonium Chloride has a density of 1.0344g/ml. WHat is the molality of Ammonium Chloride in the solution? The formula weight of NH4Cl is 53.50 g/mol??

I am not sure how to incorporate the density into the problem to come up with how to start. This is a sample of a question that will appear on CHM 152 test I have on MOnday. I just need to know where to begin in my steps please......HELP!!!!!

2.32 M = 2.32 moles NH4Cl/L solution.

2.32 moles NH4Cl = 2.32 x (53.5g/mol) = 124.12 g NH4Cl
mass of 1000 mL of the solution is 1000 x 1.0344 g/mL = 1034.4 g and 123.12 g is NH4Cl; therefore, the amount of water is
1034.4-123.12 = 910.28 g H2O or 0.91028 kg solvent.
Then 2.32 moles NH4Cl/0.91028 kg solvent =2.549 m which rounds to 2.55 m.
Check my thinking carefully,

Well, it sounds like you're in a bit of a pickle! But don't worry, I'm here to help you out with a touch of humor.

To find the molality of Ammonium Chloride in the solution, you need to consider the relationship between moles, mass, and density.

First, let me grab my clown calculator. *Honk honk!* Okay, let's get started.

Step 1: Calculate the mass of the solution.
To do this, you multiply the density (1.0344 g/ml) by the volume of the solution, which is usually given to you. Just make sure you're using the same units!

Step 2: Calculate the moles of Ammonium Chloride in the solution.
To find the moles, you divide the mass by the formula weight of Ammonium Chloride (53.50 g/mol). This will give you the number of moles of NH4Cl.

Step 3: Calculate the moles of solvent.
Assuming water is the solvent, you need to subtract the moles of Ammonium Chloride from the total moles of solution to get the moles of water.

Step 4: Calculate the molality.
Finally, divide the moles of Ammonium Chloride by the moles of water to get the molality of the solution.

There you have it! Remember to double-check your units and calculations before submitting your answer. And don't forget to add a touch of clownishly good luck to your exam! *Sprinkles confetti*

To determine the molality of Ammonium Chloride in the solution, you need to use the formula:

Molality (m) = Moles of solute / Kilograms of solvent

To calculate molality, we first need to find the moles of Ammonium Chloride in the solution. We can use the formula weight of NH4Cl to convert the density of the solution to moles.

Step 1: Calculate the mass of the solution
To find the mass of the solution, we need to multiply the density by the volume.

Mass of solution = density * volume

Step 2: Calculate the moles of NH4Cl
To calculate the moles of NH4Cl, divide the mass of NH4Cl by its formula weight.

Moles of NH4Cl = Mass of NH4Cl / Formula weight of NH4Cl

Step 3: Calculate the kilograms of water solvent
To calculate the kilograms of water solvent, divide the mass of water by the density of water.

Kilograms of water = Mass of water / Density of water

Step 4: Calculate the molality of NH4Cl
Finally, divide the moles of NH4Cl by the kilograms of water solvent to calculate the molality.

Molality (m) = Moles of NH4Cl / Kilograms of water

Now, you can apply these steps and calculate the molality of Ammonium Chloride in the solution.

To determine the molality of Ammonium Chloride in the solution, we need to use the formula:

molality (m) = moles of solute / mass of solvent (in kilograms)

In this problem, the solute is Ammonium Chloride, and the solvent is water.

Step 1: Calculate the mass of the solution.
We know that the density of the solution at 20ºC is 1.0344 g/ml. Since the question provides no information about the volume of the solution, we will assume a convenient value of 1 liter (1000 ml) for the volume.

mass of solution = density × volume = 1.0344 g/ml × 1000 ml = 1034.4 g

Step 2: Calculate the mass of the solvent.
Since the solution is Ammonium Chloride dissolved in water, we need to deduct the mass of Ammonium Chloride to find the mass of water.

mass of NH4Cl = moles of NH4Cl × formula weight of NH4Cl = 2.32 M × 53.50 g/mol

Now, we need to convert the mass of NH4Cl to grams.

mass of NH4Cl = (2.32 mol/L × 53.50 g/mol) = 123.92 g

mass of solvent (water) = mass of solution - mass of NH4Cl = 1034.4 g - 123.92 g = 910.48 g

Step 3: Convert mass of the solvent to kilograms.
Since the molality is defined as moles of solute per kilogram of solvent, we need to convert the mass of the solvent from grams to kilograms.

mass of solvent (water) = 910.48 g ÷ 1000 = 0.91048 kg

Step 4: Calculate the moles of Ammonium Chloride.
moles of NH4Cl = concentration × volume = 2.32 M × 1 L = 2.32 mol

Step 5: Calculate the molality.
molality (m) = moles of NH4Cl / mass of solvent (in kg) = 2.32 mol / 0.91048 kg

Now, plug in these values into your calculator to get the final answer!

Remember, when you attempt the problem on your test, make sure to include appropriate units and significant figures in your final answer. Double-check your calculations to avoid any errors. Good luck!
