Answer:
0.0018 moles
Explanation:
Given data:
mass of aspirin= 0.325 g
molar mass of aspirin= 180.1589 g/mol
number of moles=?
Formula:
number of moles= mass in gram/ molar mass (g/mol)
Solution:
now we will put the values in given formula:
number of moles of aspirin= mass of aspirin/ molar mass of aspirin
number of moles= 0.325 g/ 180.1589 g/mol
number of moles = 0.0018 mol
Mole:
Mole is the unit of amount in chemistry. it is SI unit and represented by "mol".
Example;
one mole of hydrogen has a mass of 1.008 g and contain 6.022× 10∧23 atoms.
