Dear professor Steffen:
Thank you for your useful page.
In this table there appear to by a mistake: 35% ammonia and 30% ammonia share the same density.
Beste wishes.

PD EXCUSEME THE PREVIOUS ERROR.

Dear Sir,
many thanks for your comment. You can find in the MSDS from different vendors values from 0.89 – 0.88 for both concentrations. My Source is from Merck “Tabellen für das Labor. In this book i found the given values.
