Question 169030
Molar mass of aspirin = (9 x atomic weight of carbon) + (8 x Atomic weight of hydrogen) + (4 x atomic weight of oxygen)

Using your table of atomic weights you can then find the Molar Mass of Aspirin to the required accuracy.
Moles = Volume(litres) x Molarity
={{{(10/1000) x 0.100}}}
=0.00100 moles of aspirin
