In the chemical formula NH4NO3, how many atoms of each element are present?

• A. 2 nitrogen, 4 hydrogen, 3 oxygen
• B. 1 nitrogen, 4 hydrogen, 3 oxygen
• C. 1 nitrogen, 4 hydrogen, 2 oxygen
• D. 2 nitrogen, 3 hydrogen, 4 oxygen

Answer: (A)

Verified step by step guidance

1. Identify the elements present in the chemical formula NH4NO3. The elements are nitrogen (N), hydrogen (H), and oxygen (O).
2. Break down the formula into its parts: NH4 and NO3. NH4 is the ammonium ion, and NO3 is the nitrate ion.
3. Count the atoms of each element in NH4: there is 1 nitrogen (N) and 4 hydrogens (H).
4. Count the atoms of each element in NO3: there is 1 nitrogen (N) and 3 oxygens (O).
5. Add the atoms from both parts together: total nitrogen atoms = 1 (from NH4) + 1 (from NO3) = 2 nitrogen atoms; hydrogen atoms = 4; oxygen atoms = 3.
