An ammonia solution has a relative density (specific gravity) of .795 at 15°C in water, with 42% ammonia. What is the appropriate ID number for this material?
Understand the Problem
The question is asking for the appropriate ID number for a specific ammonia solution based on its relative density and concentration. This involves knowledge of chemical identification standards.
Answer
UN 3318
The appropriate ID number closest to the description is UN 3318.
Answer for screen readers
The appropriate ID number closest to the description is UN 3318.
More Information
UN 3318 is for ammonia solutions with high concentrations and specific gravity, applicable here given the 42% concentration.
Tips
Ensure that the concentration and relative density match exactly for UN number identification.
