How many grams of salt can be dissolve in 20mL?

The amount of salt that can dissolve in 20mL of water depends on the solubility of the salt at that temperature. For common table salt (sodium chloride), approximately 36 grams can dissolve in 20mL of water at room temperature.


What volume in mLs of 0.100 M sodium hydroxide solution must be added to 20.0 mL of 0.08 M sulfuric acid solution to reach the end point?

To neutralize the sulfuric acid completely, you need a 1:2 molar ratio of sodium hydroxide to sulfuric acid. Therefore, you would need to add twice the amount of sodium hydroxide compared to the amount of sulfuric acid, which is 40.0 mL of the sodium hydroxide solution.


Is 50ml of water and 20ml of salt is concentrated?

Yes, a solution is considered concentrated when there is a large amount of solute (salt in this case) dissolved in a given amount of solvent (water in this case). With 20ml of salt in 50ml of water, the concentration of the solution would likely be high.


How many mL of 3N HCl is required to neutralize 20mL of NaOH?

The formula for this question is c1v1= c2v2 c1v1= 20ml x 0.01m = 0.02 x 0.01 c2v2= 0.03c2 therefore it is (0.02 x 0.01) / 0.03 = c2 c2 is the molarity of our na-oh solution cheers :D The formula for this question is c1v1= c2v2 c1v1= 20ml x 0.01m = 0.02 x 0.01 c2v2= 0.03c2 therefore it is (0.02 x 0.01) / 0.03 = c2 c2 is the molarity of our na-oh solution.


How many moles of lithium are in 20ml of 0.5mM lithium phosphate?

To determine the number of moles of lithium in 20mL of 0.5mM lithium phosphate, first calculate the moles of lithium in 1mL of the solution: 0.5mM = 0.5 mmol/L = 0.5 × 10^-3 mol/L = 5 × 10^-4 mol/L Now, for 20mL: 5 × 10^-4 mol/L × 20 mL = 0.01 moles of lithium
