To convert grams to litres at STP, you first find the number of moles by dividing the given mass by the molar mass. Then, you multiply the moles by 22.4 litres, because one mole of any gas occupies that volume at STP. But remember, my bhalu, this is only for gases—like our worries, some things only expand under certain conditions. This reminds me of my adding machine: the neat, fixed rules bring order, just as 22.4 gives a steady measure, while our tapioca yield, though measured in kilos, never converts so simply to rupees.
