What mass of a 0.66 molality ammonium nitrate (80.04g/mol) solution will contain 0.15 mol of solute?
Well, with all those numbers and formulas, I feel like I'm back in chemistry class! Let's figure this out together.
First, we know that the molar mass of ammonium nitrate is 80.04 g/mol. Given that we have 0.66 molality, it means we have 0.66 moles of ammonium nitrate in 1 kg of water.
Now, we want to find how much mass of the solution contains 0.15 mol of ammonium nitrate. To do that, we can use the formula:
mass of solution (in kg) = molality x molar mass of solute
So, let's plug in our values:
mass of solution (in kg) = 0.66 molality x 80.04 g/mol
But hold on, we want the mass in grams, not kilograms. So let's convert kg to g by multiplying by 1000:
mass of solution (in g) = 0.66 molality x 80.04 g/mol x 1000
Now we can calculate:
mass of solution (in g) = 52.8624 g
So, a 0.66 molality ammonium nitrate solution containing 0.15 mol of solute would have a mass of approximately 52.8624 grams.
That's quite a mouthful, but hey, chemistry is all about breaking things down!
To find the mass of the ammonium nitrate solution, we can use the formula:
Mass = Moles × Molar Mass
Given that the molar mass of ammonium nitrate is 80.04 g/mol, and we have 0.15 moles of solute, we can calculate the mass as follows:
Mass = 0.15 mol × 80.04 g/mol
Mass = 12.006 g
Therefore, 0.15 mol of ammonium nitrate solution will contain 12.006 grams of solute.
To determine the mass of the ammonium nitrate solution, you can use the formula:
Mass = Moles of solute × Molar mass of solute
First, let's calculate the moles of solute (ammonium nitrate) using the given information:
Moles of solute = 0.15 mol
Next, we need to find the molar mass of ammonium nitrate:
Molar mass of ammonium nitrate = 80.04 g/mol
Now, we can calculate the mass of the solution:
Mass = 0.15 mol × 80.04 g/mol
Mass = 12.006 g
Therefore, a mass of 12.006 grams of the 0.66 molality ammonium nitrate solution will contain 0.15 moles of solute.
m = mols/kg solvent
0.66 = 0.15/kg solvent
Solve for kg solvent.
Then the mass of that solution will be kg solvent + mass of the 0.15 mol solute.
mass 0.15 mol solute = mols x molar mass = ?
