What mass of nitric acid, in grams, can be made from 113g g of ammonia?
Write and balanced the equation.
Convert 113 g NH3 to mols. mols = grams/molar mass.
Using the coefficients in the balanced equation, convert mols NH3 to mols HNO3.
Now convert mols HNO3 to grams. g = mols x molar mass.
Well, let's do some chemical arithmetic, shall we? The balanced equation for the reaction between ammonia (NH3) and nitric acid (HNO3) is:
4NH3 + HNO3 → NH4NO3
The molar mass of NH3 is approximately 17 grams/mol, while the molar mass of HNO3 is approximately 63 grams/mol. From the balanced equation, we can see that 4 moles of NH3 react with 1 mole of HNO3 to produce 1 mole of NH4NO3.
So, let's calculate the number of moles of NH3 in 113 grams:
113 grams NH3 / 17 grams/mol = 6.65 moles NH3
Since the ratio of NH3 to HNO3 is 4:1, we can assume that we'll also need 6.65 moles of HNO3 to react with all the NH3. Therefore, the mass of HNO3 can be calculated as follows:
6.65 moles HNO3 x 63 grams/mol = 419.95 grams HNO3
So there you have it! Approximately 419.95 grams of nitric acid can be made from 113 grams of ammonia. Just remember, chemistry may not always make you laugh, but it sure is a gas!
To determine the mass of nitric acid that can be made from a given mass of ammonia, we need to know the balanced chemical equation for the reaction between ammonia (NH3) and nitric acid (HNO3).
The balanced equation for this reaction is:
NH3 + HNO3 → NH4NO3
From the equation, we can see that one mole of ammonia reacts with one mole of nitric acid to produce one mole of ammonium nitrate.
Step 1: Convert the given mass of ammonia to moles.
To do this, we need to know the molar mass of ammonia, which is 17.03 g/mol. We can calculate the number of moles of ammonia using the following formula:
Number of moles = Mass / Molar mass
Number of moles of ammonia = 113 g / 17.03 g/mol ≈ 6.63 mol (rounded to two decimal places)
Step 2: Determine the number of moles of nitric acid.
Since the reaction is 1:1 between ammonia and nitric acid, the number of moles of nitric acid will also be 6.63 mol.
Step 3: Convert moles of nitric acid to grams.
To do this, we need to know the molar mass of nitric acid, which is 63.01 g/mol. We can calculate the mass of nitric acid using the following formula:
Mass = Number of moles × Molar mass
Mass of nitric acid = 6.63 mol × 63.01 g/mol ≈ 417.41 g (rounded to two decimal places)
Therefore, approximately 417.41 grams of nitric acid can be made from the given 113 grams of ammonia.
