- Applies1.7Rational Expressions
Heating Na₂CO₃·xH₂O from 4.640 g to 1.720 g of anhydrous salt means converting the mass lost to moles of water and the residue to moles of Na₂CO₃, then reducing that mole ratio to a whole number x — the same cancel-to-lowest-terms move as simplifying a rational expression, where rounding a ratio like 5.98 down to 5 instead of up to 6 names the wrong hydrate.
