Depend on the kind of concentration it is expressed in. For a
1. 0.001 Molar solution, dissolve 0.001 mols of solute in enough solvent to obtain 1L of solution
2. 0.001 molal solution, dissolve 0.001 mols in 1kg of solution.

∙ 11y agoMolarity = moles of solute/Liters of solution ( 100 mL = 0.1 Liters)
Moles of solute (K2SO4) = Liters of solution * Molarity
Moles K2SO4 = 0.1 Liters * 0.1 M
= 0.01 moles K2SO4 (174.27 grams/1 mole K2SO4)
= 1.7 grams potassium sulfate
=======================Add that many grams potassium sulfate to your 100 mL.

∙ 10y agoSo you have to have a milligram for every millilitre. But you have 100ml. Therefore you have to multiply 1mg by 100, to get 100mg. Weigh out 100mg or 0.1g and dissolve it to 100ml.

How will you prepare a 100 percent solution of glucose in water?
I don't think you can. The maximum solubility of glucose in water is 91% w/v. That would mean dissolving 91g of glucose in 100ml of water. for a 100% solution you would need to dissolve 100g in 100ml, and you cant do it under normal conditions.
How do you prepare 100 mL 3M hydrochloric acid?
To prepare a 3% acetic (ethanoic) acid solution, you must first standardise the ethanoic acid. This question assumes that has already been done. To make the concentration 3%, there must be 30g per 1000mL (30gL-1). Dissolve or mix in 30g of ethanoic acid per 1000ml (1L). Pipette this into aliquots of 100mL samples. You now have a 3% ethanoic/acetic acid solution.
How do you prepare a 10 percent potassium iodide solution?
Take 10 gm oF KI dissolve it in 100ml.

How many grams of NaCl would be required to make 6M solution?
It depends on the final solution Volume you want to prepare. For 100ml of a 6M NaCL solution, you add 35.1g of NaCl to water until you reach 100ml. Dissolve and autoclave for 15 mins.
How do you prepare a Normal Saline Solution being use in 100ml of distilled water?

If a solution has a concentration of 75g per 100ml what does that mean?
It means that 100mL of solution has 75g of solute dissolved in it.

How much methanol needed to make 100 ppm solution in 100ml water?
100ppm means, you need 100mg in 1oooml. Thus, for 100ml solution, you will need 10mg of methanol to make 100ppm solution.
