What is the concentration of Ammonia in parts per million at 1%?

To determine the concentration of ammonia in parts per million (PPM) at 1%, it is essential to understand the relationship between percentage and PPM. A concentration of 1% means that there is 1 part of ammonia for every 100 parts of the total mixture.

Since 1% can also be expressed as 1 part per 100 parts, it follows that to convert from a percentage to parts per million, you multiply by 10,000. Therefore, 1% ammonia is equal to 1% × 10,000 = 10,000 PPM. This conversion stems from the fact that 1 million parts can be defined as 100% of a mixture, thus allowing the simple multiplication to establish a clear relationship between the two measurements.

Therefore, the correct concentration of ammonia at 1% is accurately represented as 10,000 PPM.
