Aspirins formula is C9H8O4

300 mg Aspirin (1 gram/1000 mg)(1 mole aspirin/180.154 grams)

= 0.00167 moles aspirin

It depends on the Aspirin's manufacturer. Aspirin come in many shapes and sizes.

Yes, you can. Baby aspirin is the same as regular aspirin, just 1/4 of the regular amount (81mg instead of 330 mg). Since aspirin causes stomach bleeding, it is advisable to only take small amounts of it. 1-2 pills of baby aspirin usually works fine for me.

For children it should be 1 tablet of aspirin for adults it would have to be 2 tablets.
