Converting Grams to Moles: Example with KMnO4
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.
