Answer:

(a).molar mass=(12×9)+(1×8)+(16×4)

=180.0g

(b).moles of Aspirin

moles=mass(g)÷molar mass

=360.4÷180.0

=2.002moles

(c). molecules of Aspirin

To get molecules just multiply moles of Aspirin by Avocado number.

=2.002×6.022×10^23

=1.206×10^24 molecules

(d) number of carbon atoms

=12×9

=108 carbon
