Would you mind walking me through this? I really am lost on how to attempt this. (just started the unit)
To pick up on oobleck's answer.
mols = grams N2O5/molar mass N2O5 = ?
molecules = mols x 6.02E23 molecules/mol = ?
mols = grams N2O5/molar mass N2O5 = ?
molecules = mols x 6.02E23 molecules/mol = ?
