![]() If you had 350 L of CO at STP, then you would have #"22.4 L"/"1 mol"# and #"1 mol"/"22.4 L"#įor example if you had 6.00 mol of carbon monoxide (CO) at STP, then So, to convert between liters and moles you would use the conversion factors It has been found that 1 mol of any gas at STP (Standard Temperature and Pressure = 0 ☌ and 1 atm) occupies 22.4 L. For example if you have 17.0 mol of NaCl, then To go from moles to grams, multiply by the formula mass. To go from grams to moles, divide the grams by the molar mass.įor example, if you have 600 g of NaCl, then To convert between grams and moles, you would use the substance's molar mass. If your compound were potassium sulfide (K₂S), you would add the mass of 2 mol of potassium (2× 39.097 g) and the mass of 1 mol of sulfur (32.064 g). This would give you the mass of 1 mol of sodium chloride which would be about 58.443 g. If you had the compound sodium chloride (NaCl), you would add the mass of 1 mol of sodium and 1 mol of chlorine. And 1 mol of chlorine (Cl) has a mass of 35.453 g (the mass on the periodic table). It can be expressed as grams, liters, atoms, molecules, or particles.įor example, 1 mol of sodium (Na) has a mass of 22.9898 g (the mass on the periodic table). A mole can be defined as the amount of substance.
