Question #ee3be

Answer 1

`n = 27.75 mol`.

Explanation:

We have:
Mass (m) = 500g
Relative Formula Mass of Water (Mr) = 18.02.

We know that, to calculate the amount of moles, we can use the formula:
`n = m/(Mr)`,
where `n` is the number of moles, `m` is the mass, and `Mr` is the relative formula mass (or molecular weight). So, we get:
`n = 500/18.02`,
`n = 27.75 mol`.
There are 27.75 moles of water in 0.5 liters of water.

Hope it Helps! :D .
