市售之藥用酒精濃度為95%
95%*100=75%*V
V=126.7
取95%之藥用酒精100ml 加水稀釋至126.7ml即可

消毒水200ppm的氯水之製作
市面上並無純酒精或純氯水販售
也不可能有純酒精或純氯水
因為酒精製造時會與水產生共沸物
而氯水為氯的水溶液
因此氯水只能稀釋
設市售之氯水為10%
10%*1=0.0002*V
V=500
將市售氯水稀釋 至原體積 500倍即可
設市售之氯水為20%
20%*1=0.0002*V
V=1000
將市售氯水稀釋 至原體積1000倍即可
其他依比例計算

200ppm消毒水：0.02g的純消毒水+99.98g水
(可以乘以倍數自己放大數量)
