is the mass of of aspirin.
Further Explanation:
Avogadro’s number is a mathematical number that determines the number of atoms or molecules in one mole of the substance. The value of Avogadro’s number is . These units can either be atoms or molecules.
There are in one mole of aspirin. Therefore the number of moles in of aspirin can be calculated as follows:
The moles of aspirin can be calculated by the following formula.s
…… (1)
Rearrange equation (1) for the mass of aspirin.
…… (2)
The molar mass of aspirin can be calculated as follows:
…… (3)
Substitute 12.01 g for the atomic mass of C, 1.008 g for the atomic mass of H and 15.99 g for the atomic mass of O in equation (3).
Substitute 0.002823 mol for the moles of aspirin and 180.114 g/mol for the molar mass of aspirin in equation (2).
Therefore the mass of aspirin is 0.508 g.
