    Dear professor Steffen:

    Thank you for your useful page.

    In this table there appear to by a mistake: 35% ammonia and 25% ammonia share the same density.

    Beste wishes.

    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.
