Answer:
1.53 * 10^-3 moles of H20
Explanation:
I see that you're using the factor-label method, so if you want to convert a number into another number, let's start with the first number.
We have 9.20 * 10^20 molecules of water.
6.02 * 10^23 particles or molecules of water is 1 mole
If we want moles, we can write it like this
9.20 * 10^20 molecules of H20 | 1 mole of H20
| 6.02 * 10^23 molecules of H20
= 1.53 * 10^-3 moles of H20
