"Describe the preparation of 100ml of the diluted HNO3 acid solution
with a mole ratio of one HNO3 to three H2O from a concentrated solution
that has a specific gravity of 1.42 and is 70% HNO3(W/W).
The specific gravity of the pure nitric acid is 1.50. "
这是清大的考古题
可是我一直不会运用比重来算 >.<
请各位大大解救一下 谢谢 m(__ __)m
