Ca no3 2 number of atoms
WebAnswer (1 of 4): For every 1 Ca(NO3)2 there are six (2 * NO3 or 2 * 3 O) oxygens. If you have 3 mole of Ca(NO3)2 then you have 18 mole of oxygen atoms (3*6). WebDec 2, 2024 · N O3 has 3 atoms of oxygen in it per molecule (indicated by the subscript of 3) and (N O3)2 means you have 2 N O3 molecules, meaning you double the subscript to get 6 oxygen atoms. Following the same rules, there is 1 atom of nitrogen in 1 N O3 molecule (subscripts of 1 are not given) and 2 atoms of nitrogen in 2 N O3 molecules. Answer link.
