The Attempt at a Solution

Do I not need density to use formula for saturation magnetization and manulipate to work out magnetic monent?

 

[mfb]

You don't need the density as you don't need a volume.

How many atoms of nickel are there in 1kg?

If the magnetic moments are all aligned, ...

Ok do I use avogardos number? Multiply that by atomic weight and divide into 1kg? Thanks for reply

 

[mfb]

Not in the way you described it, but yes you'll need the Avogadro number.

Cracking up, solution please

An atom of nickel has a mass of 58.7 u.
What is the mass of 1u, expressed in kg? Or alternatively, the mass of 1kg, expressed in u?
As a result of that, what is the mass of one atom of nickel in kg?
How many atoms do you need for 1kg?
