Web• The molar mass of a substance in grams has the same numerical value as its relative atomic (molecular) weight Molar Volume one mole of any gaseous substance occupies the same volume at the same temperature and pressure..22.414 litres at 101.325 kPa, 0 °C (273.15 K) (Avogadro’s Law) 5 P . V = n . WebThey want you to do this, then divide by the molecular mass to work out how MUCH of the substance you have. So if you have a mass and divide by a mass, you must get a number. In this case if you measure in grams and divide by the molecular/relative formula mass you'll get how many moles of substance there are. christopher stokes funeral
