Question

There are 100 mg of caffeine in a shot of espresso. The chemical formula

for caffeine is C8H10N402. How many moles of carbon are present in the
caffeine in a shot of espresso?

Answer 1

Solve a problem with the first 100th on my phone and the phone is a bit annoying and I have to use it to get the battery back.

Answer 2

there are 8 moles of carbon in the molecule because the ratio of carbon per the whole caffine molecule is 8 carbon atoms: 1 molecule of caffine so in terms of moles that's 8:1 :)
