※ 引述《samsamdir (智者恆者勝者)》之銘言：
: A 51.24g sample of Ba(OH)2 is dissolved in
: enough water to make 1.20 liters of solution.
: How many mL of this solution must be diluted
: with water in order to make 1.00 liter of
: 0.100 molar Ba(OH)2?
: 請問高手你們算多少?
: 可以列出式子嗎?
51.24/171=0.3 mole
0.3 moleBa(OH)2溶於1.20 liters水
所以400mL的此溶液含有0.100 molar Ba(OH)2
400mL的此溶液加水稀釋至1L
