WebFind out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KMnO4 is 158.032 g/mol. Divide the given mass (25.0 g) by the molar mass (158.032 g/mol) to get the moles. The number of moles of KMnO4 will be 0.158

WebAnd it gives the conversion factor of 1 / 58.5. Now multiply 25 g with 1 /58.5, which is same as dividing 25 / 58.5. This tells us that there are 0.427 moles of NaCl in the solution. Now you can use these numbers in the equations: Molarity = moles of solute / litres of solution. Molarity = 0.427 / 2 = 0.214 M. WebJan 31, 2024 · Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol. Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol. This is the number of moles in 100 g of water.
