Question

How many moles of water are in 1.23x10^18 water molecules

Answer 1

2* 10^-6

Step-by-step explanation:

Answer 2

Answer:
`0.20* 10^(-5)moles`

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number
`6.023* 10^(23)` of particles.

To calculate the moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}`

`\text{Number of moles}=(1.23* 10^(18))/(6.023* 10^(23))=0.20* 10^(-5)moles`

Thus the moles of water are
`0.20* 10^(-5)`
