It is easier to determine this if we draw the structural formula of lactic acid as shown in the attached picture. There are three functional groups in lactic acid: carboxyl group, hydroxyl group, and the parent alkane chain. Any of the hydrogens in the alkane chain is the least acidic. Then, it is followed by the H in the hydroxyl group. The most acidic is the H in the carboxyl group.

Answer:
Mass of compound c = 6 g
Explanation:
Given:
Mass of compound a = 2.5 g
Mass of compound b = 3.5 g
Find:
Mass of compound c
Computation:
According to Law of conservation of mass
Mass of compound a + Mass of compound b = Mass of compound c
Mass of compound c = 2.5 + 3.5
Mass of compound c = 6 g
