Question

Plz answer thx


​How many moles are in 2.5 x 10^18 grams of water?

Answer 1

`1.39* 10^(17)` moles of water in
`2.5* 10^(18) g` of water.

Step-by-step explanation:

Mass of water =
`m = 2.5* 10^(18) g`

Molar mass of water = M = 18 g/mol

Moles = n =
`(m)/(M)`

`n=(2.5* 10^(18) g)/(18 g/mol)=1.39* 10^(17) moles`

So, there are
`1.39* 10^(17)` moles of water in
`2.5* 10^(18) g` of water.
