Can some please check my answers for the following questions? THANK YOU.

1)The chemical formula for aspirin is C9H8O4. What is the mass of 0.40 mol of aspirin?

2)The gram molecular mass of oxygen is.

3)What is the mass, in grams, of 3.01 x 10^23 molecules of water?

2) No. Oxygen is naturally occuring as a molecule, O2, molecular mass 32

1) No. Mole mass of asprin is much more, close to 180 grams per mole. Recalculate.

3) yes.
