Molarity=[w/GMW]*[1000/volume(in mL)] 0.5=[w/342]*[1000/100]=17.1g similarly,34.2g sucrose is to dissolved in water and made up to 100mL to make 1molar solution and 171g to make 5molar solution.
To make a percent sucrose solution, dissolve a specific weight of sucrose in a specific volume of water. For example, to make a 10% sucrose solution, dissolve 10 grams of sucrose in 90 mL of water. The formula to calculate the amount of sucrose needed is: (percent sucrose/100) x volume of solution = weight of sucrose (in grams).
Ethanol is the solvent and sucrose is the solute.
Take 5 grams of calcium chloride and dissolve it in 100ml of solution to get a 5% solution of calcium chloride. The standard way to make a weight-volume solution is to take grams of the dry substance in 100ml of volume.
First, calculate the mass of HCl in 100 g of the solution: 18.25% of 100 g is 18.25 g. Convert the volume to liters: 1.2 g/mL = 1.2 kg/L. Calculate molarity using the formula Molarity (M) = (moles of solute)/(volume of solution in liters), where moles of solute = mass of HCl in grams / molar mass of HCl and volume of solution = mass of solution in grams / density of solution in g/mL.
The concentration of the solution can be calculated by dividing the mass of the solute (12 grams) by the volume of the solution (3.3 mL) and converting to the appropriate units. This will give you the concentration of ammonium sulfite in grams per milliliter.

See the two Related Questions to the left for the answer.The first is how to prepare a solution starting with a solid substance (and dissolving it). The second question is how to prepare a solution by diluting another solution.
.05 L x 342 (this is the molecular weight of sucrose) x 1.75 = 29.925g
The keyword density of sucrose in a solution refers to the concentration or amount of sucrose present in the solution. It is typically expressed as a percentage or in terms of grams per liter.
Ethanol is the solvent and sucrose is the solute.
The weight of 10 percent acetic acid solution would depend on the total volume of the solution. For example, if you have 100 grams of a 10 percent acetic acid solution, it would contain 10 grams of acetic acid.
To make 400 ml of a 50% sucrose solution, you would mix 200 ml of sucrose with 200 ml of water. Measure out 200 ml of sucrose and dissolve it in 200 ml of water, ensuring the sucrose is completely dissolved to create the 50% solution.
To find the molarity, first convert the grams of sucrose to moles using its molar mass. Sucrose has a molar mass of 342.3 g/mol. Then, convert the milliliters of solution to liters. Finally, divide the moles of solute by the liters of solution to get the molarity.
To make a 10% KI solution, dissolve 10 grams of potassium iodide (KI) in 90 grams of water, for a total of 100 grams of solution. This will give you a 10% weight/volume (w/v) solution of KI.
A 5% sucrose solution has 5 grams of sucrose in every 100 grams of solution. As 1mL of water has a mass of 1 gram, you should dissolve 5 grams of sucrose in 95 mL of water.
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
You can determine the number of grams of an active ingredient in a solution by multiplying the percent strength of the solution by the total weight or volume of the solution. This will give you the weight of the active ingredient present in the solution.
