Question

Naproxen is used to treat the pain and inflammation caused by arthritis. Naproxen has a formula of C14H14O3.

How many moles of C are present in 2.45 moles of naproxen?

How many moles of H are present in 0.377 mole of naproxen?

How many moles of O are present in 0.0675 mole of naproxen?

Answer 1

C₁₄H₁₄O₃

One mol contains 14 mol of C, 14 mol of H and 3 mol O. Using dimensional analysis, we can answer the question as follows:

2.45 moles naproxen x 14 moles C/mol naproxen = moles C

0.377 moles naproxen x 14 mol H/mol naproxen = moles H

0.0675 moles naproxen x 3 mol O/mole naproxen = moles O
