As of May 17th 1213, the price of cobalt metal on the London Metal Exchange was \$27500 per metric ton. One metric ton is defined as 1000Kg. Determine the price of cobalt in cents per atom.

• chemistry -

Look at PT and get molar mass for Cobalt. Then in your final calculation set grams= to atoms which is the same as moles.

Do you know how to set up initially?

• chemistry -

No, could you explain PT.

the molar mass for cobalt is 58.93 g/mols \
where do i go form there

• chemistry -

periodic table..you have it correct. gram/mol
moles are same thing as atoms so your last calcs will be
1kg/1000g=1gram=1mole/58.93 grams you should be left with moles which again is atoms.

• chemistry -

so it would be

27500 metric ton * 1 metric ton/1000kg *1kg/1000g*1mol/58.93g

giving you 466.655 cents in atoms?

is that right or did i mess up

• chemistry -

I got 162 cents per atom
27500X100cents/1000kg/1000g*58.93

I could be wrong but that's what Im calculating

• chemistry -

what that correct?
