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 Γ— 10^-3 mol/L = 5 Γ— 10^-4 mol/L

Now, for 20mL:

5 Γ— 10^-4 mol/L Γ— 20 mL = 0.01 moles of lithium

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

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.


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.


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.


A piece of granite weighs 52g and has a volume of 20ml what is its density?

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


A volume of 90.0 ml of aqueous koh was titrated against standard solution of h2so4 what is the molarity of the koh solution if 20.7 ml of 1.50 m h2so4 was needed?

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.
