Calculate the number of moles in 480 g ammonium nitrate
To calculate the number of moles in a substance, we need to know the molar mass of the substance.
The molar mass of ammonium nitrate (NH4NO3) can be calculated by adding up the atomic masses of its constituent elements:
- The molar mass of nitrogen (N) is approximately 14 g/mol.
- The molar mass of hydrogen (H) is approximately 1 g/mol.
- The molar mass of oxygen (O) is approximately 16 g/mol.
So, the molar mass of NH4NO3 is:
(1*14) + (4*1) + (3*16) = 14 + 4 + 48 = 62 g/mol.
Now that we know the molar mass of ammonium nitrate, we can calculate the number of moles in 480 g of ammonium nitrate by using the formula:
Number of moles = Mass (g) / Molar mass (g/mol)
Number of moles = 480 g / 62 g/mol = 7.74 moles.
Therefore, there are approximately 7.74 moles of ammonium nitrate in 480 g of the substance.
To calculate the number of moles in a substance, you need to use the formula:
Number of moles = mass of substance (in grams) / molar mass of substance
The molar mass of ammonium nitrate (NH4NO3) can be calculated by summing the atomic masses of each element in the compound. Here's the calculation:
Molar mass of N = 14.01 g/mol
Molar mass of H = 1.01 g/mol
Molar mass of O = 16.00 g/mol
Ammonium nitrate has one nitrogen atom (N), four hydrogen atoms (H), and three oxygen atoms (O). So, we calculate its molar mass as follows:
Molar mass of NH4NO3 = (1 * Molar mass of N) + (4 * Molar mass of H) + (3 * Molar mass of O)
= (1 * 14.01 g/mol) + (4 * 1.01 g/mol) + (3 * 16.00 g/mol)
= 28.04 g/mol + 4.04 g/mol + 48.00 g/mol
= 80.08 g/mol
Now, we can calculate the number of moles in 480 g of ammonium nitrate:
Number of moles = mass of substance / molar mass of substance
= 480 g / 80.08 g/mol
= 5.9949 mol (rounded to 4 decimal places)
Therefore, there are approximately 5.9949 moles in 480 g of ammonium nitrate.
