Calculating molar mass of KMnO4:

Molar mass of KMnO4 = (39.098 + 54.938 + 15.999*4) g/mol = 158.04 g/mol

Converting grams to moles:

We can now use the given mass of 25.0 grams and the molar mass of KMnO4 to convert the grams to moles using the formula:

Moles = Mass / Molar mass

Plugging in the values:

Moles of KMnO4 = 25.0 grams / 158.04 g/mol = 0.158 moles

Therefore, the answer is 0.158 moles of KMnO4 when 25.0 grams are converted.
