金虫 (小有名气)

[求助] 高手帮忙帮我翻译下下面的句子!

Sodium monohydrogen phosphate Na2HP04-12H20 (18 g) is dissolved in a mixture of perchloric acid (73 mL, 11.7 F) and water (20 mL). The solution is cooled to -10 OC. Then a solution of sodium molybdate Na2Mo04.2H20 (108 g) in water (200 mL) is added dropwise to the above solution kept at -10 OC. The resulting solutionis pale yellow.
   里面的“73 mL, 11.7F" 是什么意思,F是指什么?谢谢 !

因为你看后面还用  摄氏度, 而且即使把F换成摄氏度,感觉就不对!
   再看这句
“Na2W04.2H20 (120 g) is dissolved in water (150 mL). Orthophosphoric acid, H3P04 (3 mL,14.7 F), and concentrated acetic acid (22 mL, 17.4 F) are successively added to the solution. The white salt Na8HPW9034.24H20p recipitates out.”
   一样的这个"F"应该怎么解释?

十二水合磷酸氢二钠(18g)溶于13ml高氯酸与20ml水所配制成的溶液中。将此混合溶液冷却至-10℃。然后将108g Na2MoO4•2H2O溶于200ml水所配制的溶液在-10℃滴加至上述混合液中。最终得到的液体为浅黄色。

这里的73ml 11.7F是指在华氏11.7度下的73ml吧,因为老美有的时候还是用华氏度的。

我觉得应该不是"F" 应该不是指温度!
