Question

How many moles are in 175.9 g of Krypton?

Answer 1

2.09 moles

Step-by-step explanation:

We can find the number of moles from the given mass of the element by using the formula

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

m is the mass

M is the molar mass

n is the number of moles

The molar mass of krypton is 84 g/mol

We have

`n = (175.9)/(84) = 2.094\\`

We have the final answer as

2.09 moles
