calculate the mass of this sample:
1.05 * 10 to the power of 26 atoms of neon, Ne(g)
I know that I have to first divide by the avagadros constant, then once get the moles I need to multiply by the molar mass of neon to get the grams, I did that sevral times but I keep on getting the wrong answer... the correct answer is 3.5*10 to the power of 3.. Please show me the steps properly..:) Thanks!

The quick way of getting your answer is for you to show your work. That way we can see what you're doing wrong. This way we're working in the dark.
mols = 1.05E26/6.02E23 = ?
g = mols x molar mass = ?
That 3.5E3 grams is correct.
mols = 1.05E26/6.02E23 = ?
g = mols x molar mass = ?
That 3.5E3 grams is correct.
