Question

how many moles of aspirin, C9H8O4, contain 0.480 mole of O atoms?

Answer 1

ratio and proportion

1 mole aspirin is to 4 moles O as x is to 0.480 mol O

x = 0.120 mol of aspirin.

Into a calculator would be 0.480 divided by 4

Edit:

CM got it backwards:

"0.48moles aspirin would contain 4x moles of O, 1.92 moles"

It's not 0.48 moles of aspirin, it's 0.48 moles of oxygen
