One million atoms of a particular element have a mass of 1.99 x 10 ^-17 grams.
- how many moles of this element are there?
- what is the molar mass of this element?
- what is the identity of this element?

Moles of this element = moles

The molar mass of this element  is 12 g/mol.

Carbon is the identity of this element.

Explanation:

Number of atom = 1,000,000

Number of atoms =

Moles of this element = moles

If moles weighs =  

Then mass of 1 mol =

The molar mass of this element  is 12 g/mol.

Carbon is the identity of this element.
