One NaHCO3 has Na:1, H:1, C:1, O:3. For 3 molecules: Na=3, H=3, C=3, O=9.

Thus the true statements are:
- The number of sodium atoms (Na) equals the number of carbon atoms (C).
- The number of sodium atoms (Na) equals the number of carbon atoms (C). (the repeated phrasing)

All other statements are false.
