Find the molar mass of a water molecule (H₂O). It's ca. 18.015 g/mol. Convert the volume of the water to its mass, assuming that the density of pure water is 998 kg/m³: m = 6 l × 998 kg/m³ = 0.006 m³ × 998 kg/m³ = 5.988 kg. It's easier to work with grams, so convert the mass: 5.988 kg = 5988 g
30 wrz 2024 · The mol calculator uses the formula: \ [ m = \frac {M} {MW} \] where: \ (m\) represents the number of moles, \ (M\) is the mass of the substance in grams, \ (MW\) is the molecular weight of the substance in grams per mole. Example Calculation. To find the number of moles in 500 grams of water (\ (H_2O\)), with a molecular weight of 18.01528 g/mol:
The formula for converting grams to moles is straightforward but requires knowledge of the substance’s molecular weight. The basic grams to moles formula is: number of moles = mass in grams ÷ molecular weight. Or, expressed mathematically: n = m ÷ MW. Where: n is the number of moles. m is the mass in grams.
