What is made by adding 4.5 moles of NH3 to 250ml of water.what is the molarity?
Adding 4.5 moles of NH3 to 250 mL of water will result in a solution with a volume slightly greater than 250 mL. To calculate the molarity, you need to know the final volume of the solution. Once you have the final volume, you can use the formula: Molarity = moles of solute / liters of solution.
When NH3 dissolves in water it forms NH4OH?
Ammonium (cation): NH4+ Hydroxyl (anion): OH- It is incorrect to write NH4OH solution, because the solution is of ammonia (NH3) in water.
The percent by mass of hydrogen in NH3 is equal to?
The percent by mass of hydrogen in NH3 is 17.65%. This can be calculated by dividing the mass of hydrogen in NH3 by the total mass of NH3 and then multiplying by 100.
Will H2O and NH3 form a solution?
H2O (water) and NH3 (ammonia) can mix and form a homogeneous solution in certain circumstances, such as when diluting ammonia in water or using them as solvents. However, ammonia is a weak base and can react with water to produce ammonium and hydroxide ions.
What happens when NH3 is dissolved in water?
When NH3 is dissolved in water, it reacts with water molecules to form ammonium hydroxide (NH4OH). This reaction increases the concentration of hydroxide ions (OH-) in the solution, making it basic. Ammonium ions (NH4+) and hydroxide ions (OH-) are present in the resulting solution.
A bottle of commercial concentrated aqueous ammonia is labeled 28.89 percent NH3 by mass and density is 0.8960 grams mL. What is the molarity of the ammonia solution?
To find the molarity, first calculate the moles of NH3 in 100g of the solution using the mass percent. Then convert the volume of the solution (1 mL) to liters. Finally, divide moles by liters to obtain the molarity.
What is the molarity of a solution that contains 68g NH3 in 4.5L of solution?
The molar mass of NH3 is 17 g/mol. First, convert 68g to moles by dividing by the molar mass. Then, divide the moles of NH3 by the volume of the solution in liters to find the molarity.
What is the molarity of a solution that contains 17g of NH3 in 0.50l of solution?
To find the molarity, first calculate the number of moles of NH3 in 17g using its molar mass. Molar mass of NH3 = 17.031 g/mol. Therefore, moles of NH3 = 17g / 17.031 g/mol = 0.997 moles. Then, divide the moles of NH3 by the volume of the solution in liters to get the molarity: Molarity = 0.997 moles / 0.50 L = 1.99 M.

What is the molarity of ammonia solution if the pH is 11.6 and the Kb is 1.8x10-5?
To find the molarity of ammonia solution, first calculate the concentration of OH- ions in the solution using the pH value. From there, use the Kb value to find the concentration of NH3. Finally, convert the concentration of NH3 to molarity to get the answer.
Does nh3 have isomers?
Ammonia (NH3) hasn't an isomer.The solution of ammonia in water is called ammonium hydroxide.
When NH3 dissolves in water it forms NH4OH?
Ammonium (cation): NH4+ Hydroxyl (anion): OH- It is incorrect to write NH4OH solution, because the solution is of ammonia (NH3) in water.
If there are 20 grams of NH3 dissolved in 100 grams of water at 30 degrees C. What type of solution will you have?
You will have a dilute solution of ammonia (NH3) in water. At this temperature, the ammonia is likely to be mostly in the form of ammonium ions (NH4+). Since the amount of solute (NH3) is much less than the amount of solvent (water), it is a dilute solution.
What is the equation for the solution in water NH4OH?
NH4OH < == > NH3 + H2O, it is a weak base
Is NH3 alkaline?
Yes, ammonia (NH3) is alkaline because it reacts with water to form ammonium hydroxide (NH4OH), which is a weak base. This solution can then release hydroxide ions (OH-) which can accept protons (H+) from acids, making the solution basic.
Why would NH3 ammonia be considered an Arrhenius base?
NH3 ammonia can be considered an Arrhenius base because it dissociates in water to form hydroxide ions (OH-) and ammonium ions (NH4+). In aqueous solution, NH3 can accept a proton from water to form NH4+ and OH-, increasing the concentration of hydroxide ions and thus making the solution basic.
Formula for aqueous ammonia?
The formula for aqueous ammonia is NH3. When ammonia gas dissolves in water, it forms an alkaline solution.
