Answer:

#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 .
