This free moles to grams calculator can instantly convert moles to grams and determine how many atoms/molecules are present in these grams.
Convert grams to moles and moles to grams using a simply calculator. Plus, learn the g to mol formula and how to account for molar mass.
With this grams to moles calculator, you can swiftly find how to calculate grams to moles for any substance. It can also work the other way around as a moles to grams conversion tool!
30 lip 2024 · The amount of grams in a mole depends on the substance you have. To work it out, find the atomic or molecular mass of your substance and multiply it by the number of moles you have. For one mole, the atomic or molecular mass will be the same as the weight.
Problem: Convert 25.0 grams of KMnO4 to moles. Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). Divide the given mass (25.0 g) by the molar mass (158.032 g/mol) to get the moles.
To calculate molarity in such cases, you need to convert the mass of the solute to moles using its molecular weight (also called molar mass). The molecular weight is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).
The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. E.g. Molar mass of NaCl is 58.443, how many grams is 5 mole NaCl? grams = 58.443 × 5 = 292.215 (g)
