See if you can figure out, given all the numbers that are in this problem here, you know what, the pure pressure on the solvent is.
看看自己是否能够想出来结果，这个问题的所有数值都有了，有纯溶质的蒸汽压。

When selecting solvent attention should be paid to its solubility, steam pressure and volatility in addition to safety.
选择溶剂要注意溶解力、蒸汽压与挥发度，使用中要注意安全。
