Answer
The molecular formula for alanine is C$_{3}$H$_{7}$NO$_{2}$.
Work Step by Step
We first find the chemical symbols of each of the elements in this compounds. We have carbon (C), hydrogen (H), nitrogen (N), and oxygen (O).
Next, we figure out how many atoms of each element are in the compound. We have three atoms of carbon, seven atoms of hydrogen, one atom of nitrogen, and two atoms of oxygen. Therefore, the molecular formula for alanine is C$_{3}$H$_{7}$NO$_{2}$.
