You have three molecules of sodium bicarbonate (formula: 3 NaHCO3). Which of the following is true?

A. The number of sodium atoms (Na) equals the number of hydrogen atoms (H).

B. The number of carbon atoms (C) is three times greater than the number of oxygen atoms (O).

C. The number of oxygen atoms (O) is less than the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.

D. The number of oxygen atoms (O) is greater than the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.

***Please explain!! :) Thank you! :)

Hi again @hba !!! :) thank you so much for coming!!!! :)

what do u think? :)

hba · Answer

The answer is The number of oxygen atoms (O) equals the sum of the sodium (Na), hydrogen (H), and carbon (C) atoms.

anonymous · Answer

that's not an answer choice tho... so would that mean A is the answer?? since number of NA atoms equals number of H atoms??? (both have one atom??) @hba

3 NaHCO3 means you have 3 copies of NaHCO3 ( i think anyway..)

so that would make me think there are 3 Na, 3 H, 3 C and 3*3 = 9 O atoms
