검증된 단계별 안내1
Understand the meaning of the prefix 'micro-' in chemistry, which denotes a factor of \(10^{-6}\).
Recognize that 1 micromole (abbreviated as 1 \(\mu\)mol) means 1 times \(10^{-6}\) moles.
Write the conversion explicitly: 1 micromole = \(1 \times 10^{-6}\) moles.
Compare this value with the given options to identify the correct one.
Conclude that the number of moles in 1 micromole is \(1 \times 10^{-6}\) moles.
