Final answer:
The molar mass of
is 388.74 g/mol.
Step-by-step explanation:
The molar mass of
can be calculated by adding up the atomic masses of manganese (Mn), chlorine (Cl), and oxygen (O). The molar mass of
is:
1 mol of Mn = 54.94 g/mol
4 mol of Cl = 4 x 35.45 g/mol = 141.8 g/mol
12 mol of O = 12 x 16.00 g/mol = 192 g/mol
Therefore, the molar mass of
is 54.94 g/mol + 141.8 g/mol + 192 g/mol = 388.74 g/mol.
