The conversion factor for deriving the number of moles of salicylic acid, C7H6O3, from a given number of grams of salicylic acid is...
what is mole mass?
To convert the number of grams of a substance to moles, you need to use its molar mass.
The molar mass of salicylic acid, C7H6O3, can be calculated by summing the atomic masses of its constituent atoms:
Carbon (C) has an atomic mass of 12.01 g/mol,
Hydrogen (H) has an atomic mass of 1.01 g/mol,
Oxygen (O) has an atomic mass of 16.00 g/mol.
Calculating the molar mass of salicylic acid:
(7 * 12.01 g/mol) + (6 * 1.01 g/mol) + (3 * 16.00 g/mol) = 138.12 g/mol.
Therefore, the conversion factor is 1 mole of salicylic acid = 138.12 grams of salicylic acid.
To find the number of moles of salicylic acid (C7H6O3) from a given number of grams, we need to use the concept of molar mass.
The molar mass of a compound is the sum of the atomic masses of all the atoms in that compound. To find the molar mass of salicylic acid, we can look up the atomic masses of carbon (C), hydrogen (H), and oxygen (O) in the periodic table.
The atomic mass of carbon (C) is approximately 12.01 grams per mole.
The atomic mass of hydrogen (H) is approximately 1.01 grams per mole.
The atomic mass of oxygen (O) is approximately 16.00 grams per mole.
Now, let's calculate the molar mass of salicylic acid:
(7 × 12.01 g/mol) + (6 × 1.01 g/mol) + (3 × 16.00 g/mol) = 138.12 g/mol
Therefore, the conversion factor for deriving the number of moles of salicylic acid from a given number of grams is:
1 mol salicylic acid = 138.12 g salicylic acid
