To neutralize NaOH, which is a base, with HCl, which is an acid, we need to use an equal number of moles of each. Since the concentration of HCl is 3N, this means 3 moles of HCl are present in 1 liter. 20mL of a 3N solution of HCl would contain 0.06 moles, but that's already answered, so it would take 20mL of 3N HCl to neutralize 20mL of NaOH.
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.
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.
density = mass / volume = 52 / 20 = 2.5 g cm-3 Note the units used. Density is commonly measured in grams per cubic centimeter. However using millilitres does not affect the answer since 1 ml = 1 cm3
Using the balanced chemical equation for the reaction between KOH and H2SO4, you can determine the mole ratio. Then, using the volume and molarity of H2SO4 used, calculate the moles of H2SO4. Finally, use the mole ratio to find the moles of KOH and calculate the molarity of the KOH solution.

To calculate the number of moles of NaOH, we use the formula: moles = molarity x volume (in liters). First, convert 20 mL to liters (0.02 L). Then, use the formula to find: moles = 0.5 mol/L x 0.02 L = 0.01 moles of NaOH present in 20 ml of 0.5M NaOH.

20ml - 0.2ml = 19.8
20mL equates to about 4.1 (4.05768) US teaspoons.
5ml = 1 teaspoon 20ml = 4 teaspoons
There are 3 units of 20ml in 60ml, because 20ml x 3 = 60ml.
