How many grams of hydrochloric acid are needed to make a solution of 2 molar?
To make a 2 molar solution of hydrochloric acid, you would need to know the volume of the solution you want to make. Once you have the volume, you can use the molarity formula (M = moles of solute / liters of solution) to calculate the grams of hydrochloric acid needed.
How many milliliters of water need to be added to 895 milliliters of a 2.25 molar solution of calcium sulfate to make the solution 85 molar?
Calcium sulfate is very low soluble in water - 2,1 g/L at 20 0C.
How many grams of NaCl would you have to use to make a 4.500 molar solution containing 3200 grams of water?
You need 841,536 g NaCl.
How many gm of NaOH are required to make one liter of a solution?
As many as you like, depending on what you want the concentration to be. (Solubility will eventually become a factor, but sodium hydroxide is pretty darn soluble.)
How many grams of Glucose molecular formula C6O6H12 should you dissolve in 1 liter of water to get 1 molar solution?
To make a 1 molar solution of glucose (C6H12O6) in 1 liter of water, you would need to dissolve 180 grams of glucose. This is because the molar mass of glucose is 180 g/mol, so 1 mole of glucose weighs 180 grams.
How many grams of sodium chloride are required to make 1.0 L solution with a concentration of 3.5 m?
The molecular weight of NaCl is 58.44; sodium =22.99; Chlorine=35.45. A 1 molar solution is the molecular weight in grams in 1 litre of water, so a 3.5 molar solution would be 58.44g multiplied by 3.5, which is 204.54g in 1L.
How many moles of specified particles are present in a sample of N'O if each sample weighs 7.00 g?
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
How many carbon atoms are there in 700 liters of a 2 molar Carbonic acid solution?
1400 moles.
How many grams of KCl is needed to make 2 molar solution in 1 liter of water?
To prepare a 2 M solution of KCl in 1 liter of water, you would need to dissolve 149.5 grams of KCl. This is because the molar mass of KCl is approximately 74.5 g/mol, and 2 moles of KCl are needed to prepare a 2 M solution in 1 liter of water.
Potassium fluoride (KF a salt has a molecular weight of 58.10 grams. How many grams would be needed to make 1.0 liter of 5.0 molar salt solution?
290 grams
How many grams of magnessium chloride are in 1liter solution 2.5M?
Magnesium chloride has a molecular weight of 95.2, so 1 litre of 1 molar MgCl2 would have 95.2g. A 2.5 molar solution would have 2.5X95.2g per litre = 238grams
How many grams of sodium chloride are required to make a 1.0 L solution with a concentration of 3.5 M?
The molecular weight of NaCl is 58.44; sodium =22.99; Chlorine=35.45. A 1 molar solution is the molecular weight in grams in 1 litre of water, so a 3.5 molar solution would be 58.44g multiplied by 3.5, which is 204.54g in 1L.
