SUMMARY
The discussion centers on the application of significant figures in chemistry calculations, specifically regarding the conversion of moles to grams for potassium hydroxide (KOH). The calculation presented involves 5.8 moles of KOH, which equals 325.438 grams when multiplied by the molar mass of 56.11 g/mole. Following the rules of significant figures, the final answer is correctly rounded to 330 grams (or 3.3E2 grams), reflecting two significant figures based on the initial measurement of 5.8 moles.
