Calculate the miles of potassium hydrogen phthalate in your weighed sample.
Potassium hydrogen phthalate : 4.0759g
im assuming you mean "moles" not "miles"
(4.059g sample/1)x(1 mole sample/g of sample in one mole(take number of elements in formula multiplied by individual grams found in the periodic table)). there is your answer. easy as pie.
To calculate the miles of potassium hydrogen phthalate in your weighed sample, you will need to know the molar mass of potassium hydrogen phthalate and the number of moles present in the sample.
The molar mass of potassium hydrogen phthalate (KHC8H4O4) can be calculated by summing up the atomic masses of its constituent elements.
Potassium (K) has an atomic mass of 39.1 g/mol.
Hydrogen (H) has an atomic mass of 1.01 g/mol.
Carbon (C) has an atomic mass of 12.01 g/mol.
Oxygen (O) has an atomic mass of 16.00 g/mol.
KHC8H4O4 has:
1 potassium atom (1 * 39.1 g/mol) = 39.1 g/mol
8 carbon atoms (8 * 12.01 g/mol) = 96.08 g/mol
4 hydrogen atoms (4 * 1.01 g/mol) = 4.04 g/mol
4 oxygen atoms (4 * 16.00 g/mol) = 64.00 g/mol
Adding these values together:
39.1 g/mol + 96.08 g/mol + 4.04 g/mol + 64.00 g/mol = 203.22 g/mol
So, the molar mass of potassium hydrogen phthalate is 203.22 g/mol.
To calculate the number of moles of potassium hydrogen phthalate in the sample, divide the mass of the sample by its molar mass:
Number of moles = Mass (g) / Molar mass (g/mol)
For the given sample:
Mass = 4.0759 g
Molar mass = 203.22 g/mol
Number of moles = 4.0759 g / 203.22 g/mol ≈ 0.020 moles
Therefore, there are approximately 0.020 moles of potassium hydrogen phthalate in your weighed sample.
To convert moles to miles, you would need additional information such as the density or volume of potassium hydrogen phthalate. The conversion from moles to miles is not possible without this information.
