Question

How many moles are there in 88.5 grams of water?

Answer 1

`4.92\text{ moles}`

Step-by-step explanation:

Here, we want to get the number of moles in the given mass of water

To get this, we have to divide the mass given by the molar mass of water

Mathematically:

`Number\text{ of moles = }\frac{mass}{molar\text{ mass}}`

The molar mass of water is 18 g/mol

Thus, we have the number of moles as:

`Number\text{ of moles = }(88.5)/(18)\text{ = 4.92 moles}`
