Problem 2) Problem 5-3: What is the concentration of NH3 (in mg/L) of household ammonia that contains 3.00 percent by weight of NH3? Assume the density of water 5 1,000 kg/m3.
Household ammonia, which is also referred to as ammonium hydroxide (NH4OH), typically represents a diluted solution of ammonia gas (NH3) within water. The concentration of ammonia in household ammonia may exhibit some variability, but it is generally found to be within the range of 3% to 10% ammonia by weight. To put it in perspective, for every 100 grams of household ammonia, you can expect to find anywhere from 3 to 10 grams of ammonia gas.
The density of household ammonia is subject to variation based on its precise formulation and the prevailing temperature conditions. However, it is generally in the range of approximately 0.91 to 0.96 grams per milliliter (g/mL) when measured at room temperature (around 20°C or 68 °F). This density range is indicative of the usual concentrations of ammonia encountered in household ammonia solutions.
