Molarity = (Mass of solute in grams) / (Molar mass of solute in grams / Volume of solution in liters)

Rearranging the formula to solve for the molar mass, we get:

Molar mass = (Mass of solute in grams) / (Molarity * Volume of solution in liters)

Substituting the given values into the formula, we get:

Molar mass = (25.0 g) / (0.290 M * 0.750 L)

Molar mass = 135.93 g/mol

Therefore, the molar mass of the compound is 135.93 g/mol.
