[CJHski]

some chemistry help please.........and i know someone just made a thread about chem. help but it dosent help me.......

alright so for this problem ......Find the total number of atoms in 2.0 moles of calcium nitrate?...... i got 272.06 atoms in 2 moles of Ca(NO3)2........why is this wrong?

 

[pommes_vertes.]

its 1.0836 * 10^25.

there are 9 atoms per calcium nitrate molecule (1 calcium, 2 nitrogen, 6 oxygen). each mole has 6.02 * 10^23 molecules. two moles. multiply them.
