How many moles of NH3 are in 2ml of supplied solution: 0.2 M NH3 in 2 M Nh4NO3
Ans to be given in mmol
Homework Equations
Concentration = mol/ L
The Attempt at a Solution
Ratio of NH3 : NH4NO3 = 1: 10
2 / 11 = 0.182 ml
0.2 mol/L * 1L/ 1000ml * 0.182 ml * 1000 = 0.0364 mmol
To calculate the number of moles of NH3 in a solution, you can use the formula moles = molarity x volume. In this case, the molarity is 0.2 M and the volume is the total volume of the solution, which is not provided.
NH3 and NH4NO3 are both chemical compounds. NH3, also known as ammonia, is a gas that is commonly used in fertilizers, household cleaners, and other industrial processes. NH4NO3, also known as ammonium nitrate, is a solid compound that is also used in fertilizers but can also be used as an explosive.
The concentration of NH3 in a solution can affect its properties in various ways. As the concentration increases, the solution may become more basic and have a higher pH. It may also have a stronger smell due to the presence of ammonia. Additionally, the concentration can affect the solubility of other compounds in the solution.
The concentration of NH3 in a solution is typically measured using a device called a pH meter. This device measures the concentration of hydrogen ions in the solution, which can be used to determine the concentration of NH3. Other methods of measurement include titration, where a known solution is added to the solution until a reaction occurs, and spectrophotometry, where the amount of light absorbed by the solution is measured.
Yes, the concentration of NH3 in a solution can change over time. This can occur due to various factors such as evaporation, chemical reactions, or changes in temperature. To maintain a specific concentration, the solution may need to be stored properly and the concentration may need to be periodically checked and adjusted.
