Answer:
1.08 x 10^24
Step-by-step explanation:
The number of molecules in a given amount of a substance can be determined by using Avogadro's number, which is approximately 6.022 x 10^23 particles per mole.
To find the number of molecules in 1.8 moles of water, you would use the following calculation:
1.8 moles x 6.022 x 10^23 particles/mole = 1.0839 x 10^24 molecules
So there are about 1.08 x 10^24 molecules in 1.8 moles of water.
