![]() The number of grams of KClO3 will be 306. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.The molar mass of KClO3 is 122.548 g/mol. Problem: Convert 2.50 moles of KClO3 to grams. Click here to learn more about the molarity calculators. The number of moles of KMnO4 will be 0.158Īnd here is how you should enter this problem into the calculator above: grams to moles problem solution Moles to grams example problem The calculator will autopopulate other fields where possible. Divide the given mass (25.0 g) by the molar mass (158.032 g/mol) to get the moles.The molar mass of KMnO4 is 158.032 g/mol. Problem: Convert 25.0 grams of KMnO4 to moles.įind out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: standard relative atomic masses are dimensionless quantities (i.e., pure numbers), whereas molar masses have units (in this case, grams/mole).Īnd this is where our grams to moles/moles to grams calculator shines, thanks to our other calculator - Molar mass of the substance, which calculates molar mass for a substance given the formula.Īll you need to do is correctly enter your formula, choose whether you want a conversion from grams to moles or a conversion from moles to grams, and, in case of g to mol, enter the mass, or, in case of mol to g, enter the moles. The molar mass of a compound is given by the sum of the standard atomic weight (namely, the standard relative atomic mass) of the atoms which form the compound multiplied by the molar mass constant. MASS Research Review: Train Smarter With Science Easily interpret and apply the latest training and nutrition research Get concise and applicable breakdowns of the latest strength, physique, and nutrition research delivered monthly. The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol. The molar mass is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. MS-FINDER was launched as a universal program for compound ‘annotation’ that supports EI-MS (GC/MS) and MS/MS spectral mining. You need to multiply the molar mass of the substance by the number of moles:Īs you can see, the most difficult task here is finding out the molar mass of the substance. You need to divide the mass of the substance by the molar mass of the substance: molar mass of the substance in grams/mole How to convert grams to moles? Mass Number calculator uses Mass Number Number of Protons+Number of Neutrons to calculate the Mass Number, The Mass number is the sum of the number of protons and neutrons in an atom of an element. There is a simple relation between grams and moles:
