To determine the molar mass of an element or compound, you need to sum up the atomic masses of all the atoms in the formula. Since you haven't provided any specific compound or formula involving elements A, B, and C, I'll assume you want to find the molar mass of a hypothetical compound made up of one atom each of elements A, B, and C.
To calculate the molar mass of this compound, you simply add up the atomic masses of A, B, and C:
Molar mass = Atomic mass of A + Atomic mass of B + Atomic mass of C
Given the atomic masses you provided: Atomic mass of A = 32 g/mol Atomic mass of B = 25 g/mol Atomic mass of C = 57 g/mol
Molar mass = 32 g/mol + 25 g/mol + 57 g/mol Molar mass = 114 g/mol
Therefore, the molar mass of the hypothetical compound composed of elements A, B, and C would be 114 g/mol.
