n = 27.75 moln=27.75mol.

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)n=mMr,
where nn is the number of moles, mm is the mass, and MrMr is the relative formula mass (or molecular weight). So, we get:
n = 500/18.02n=50018.02,
n = 27.75 moln=27.75mol.
There are 27.75 moles of water in 0.5 liters of water.

Hope it Helps! :D .
