The answer is 1,668.10-4 moles.
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.
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.
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.
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.
