How do you prepare 2N ammonium hydroxide solution from 25 percent ammonium solution?
Reference: the density of 25% NH4OH solution = 0.907g/cm³ Therefore 1 litre of solution has mass 907g 25% = 25/100*907 = 226.75g NH3 in 1 litre solution Molar mass NH3 = 17.031 g/mol 226.75g = 226.75/17.031 = 13.31N solution To make 1 litre of 2N solution: ( Work in ml= 1000ml) N1V1 = N2V2 13.31*V1 = 2*1000 V1 = 2000/13.31 V1 = 150.2ml Measure out 150.2ml of the 25% solution and dilute to 1 litre. This is a 2N solution.
Now assume you measure out exactly 2.0 ml of aluminum chloride into a third test tube How many moles of aluminum chloride are in the tube?
To calculate the number of moles of aluminum chloride in the test tube, you need to know the molar mass of aluminum chloride (AlCl3). The molar mass of AlCl3 is 133.34 g/mol. Given that you have 2.0 ml of AlCl3, you will need to convert this volume to grams using the density of AlCl3. Finally, you can calculate the moles using the molar mass.
How many grams of sodium chloride are needed to prepare 600 ml of a 0.9 percent saline solution?
600 mL of 0,9 % sodium chloride: 6 x 0,9 = 5,4 grams NaCl
What are some ways to find density of NaCl which is water soluble?
One way to find the density of NaCl is to dissolve a known mass of NaCl in a known volume of water to make a solution. Then, measure the volume of the solution and calculate the density using the formula: Density = mass of solution / volume of solution. Another way is to look up the density of a standard solution of known concentration.
Density of calcium chloride?
Calcium density: 1,55 g/cm3 at room temperature.
What is the density of ammonium hydroxide?
The ammonium hydroxide solution 28 % has a density of 0,9 g/cm3 at 25 oC.
What is the density of barium chloride in water?
The density of barium chloride in water depends on the concentration of the solution. A common concentration of barium chloride solution is 1M, which has a density of around 1.32 g/mL. Higher concentrations will have higher densities due to the increased mass of barium chloride dissolved in the water.
What is the relationship between the mass and volume of a sodium chloride solution?
Density=Mass/Volume
What is the density of 5 salt water?
The density of a 5 % sodium chloride solution is 1,0340 g/cm3 at 20 0C.
What is the density of 1 M solution of zinc chloride?
Density is about 1.1 g/mL. We just made a batch of this in my lab.
What is the volume of 19.87 mol of ammonium chloride at STP?
The molar volume of a gas at STP (Standard Temperature and Pressure) is 22.4 L/mol. However, ammonium chloride is a solid at STP, and therefore does not follow the ideal gas law. To calculate the volume of a solid like ammonium chloride, we need to know the density.
Can you determine the density of zinc chloride using water?
Yes, you can determine the density of zinc chloride by measuring the mass of a known volume of the solution. Since zinc chloride is soluble in water, you can create a solution with a known concentration of zinc chloride, measure its mass and volume, and then calculate the density using the formula density = mass/volume.
What is the ideal keyword density of sodium chloride solution in order to optimize its effectiveness in a solution?
The ideal keyword density of sodium chloride solution to optimize its effectiveness is typically around 0.9 to 1.5. This concentration is commonly used in various applications such as saline solutions for medical purposes or in laboratory settings.
Could you determine the density of zinc chloride using water as a solvent?
Yes, the density of zinc chloride can be determined by measuring the mass of a known volume of the solution (a mix of zinc chloride and water) and then calculating the density using the formula: Density = mass/volume.
What is the density of chloride?
Chloride is an ion. It cannot exist alone, but must be with some positive ion. Potassium chloride, sodium chloride, lithium chloride, copper (II) chloride, etc. are compounds and each has a certain density.
What is the density of ferric chloride?
The density of ferric chloride is approximately 2.8 g/cm³ at room temperature.
Why does sodium chloride sink?
1. Because the density of sodium chloride is higher than the density of water. 2. Sodium chloride is soluble in water.
