Question

How many moles in 518 grams of CaCO3

Answer 1

`5.18\text{ moles}`

Step-by-step explanation:

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

Mathematically:

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

The molar mass of CaCO3 is 100 g/mol

The number of moles is thus:

`Number\text{ of moles = }(518)/(100)\text{ = 5.18 moles}`
