Answer:

Molecular mass of \(KHCO_{3}\) is 100 g.

Explanation:

Molecular mass of a molecule is the summation of atomic masses of all constituting atoms.

Molecular mass of  \(KHCO_{3}\)= (Atomic mass of K)+(Atomic mass of H)+(Atomic mass of C)+ (\(3\times\)Atomic mass of O)

So, molecular mass of \(KHCO_{3}\) = (39 g)+(1 g)+ (12 g)+(\(3\times\) 16 g) = 100 g
