∙ 10y agoTo calculate the total amount of sodium bicarbonate in the 20ml polyfuser, you first need to convert the percentage concentration to mg/ml.
8.4% of sodium bicarbonate means 8.4g of NaHCO3 in 100ml of solution.
Convert 8.4g to mg (8.4g * 1000 = 8400mg), then divide by 100ml to get 84mg/ml.
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.
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.
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.
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.
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

The rise in temperature is affected by the amount of anhydrous sodium carbohydrate added to 20ml of water
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.
