The problem is:
Convert to grams:
4.3 x 10^22 atoms of nitrogen (N^2)
PLEASE HELP VERY URGENT

I guess you don't know that one mole of anything equates to 6.02 x 10^23
so find the number of moles of atoms you have
4.3 x 10^22 / 6.02 x 10^23 then multiply that by the molar mass of N.

Divide by Avogadro's number to get moles.
Multiply by the molar mass of N2 to get the mass of N2 in grams.

that's 1g...
4.3x10^22 / 6.02x10^23 = 0.0714mol
0.0714 * 14 = 1g
4.3x10^22 / 6.02x10^23 = 0.0714mol
0.0714 * 14 = 1g
