Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC,H_O4. This is often written in shorthand notation as KHP. What volume of a 0.297 M potassium hydroxide solution is needed to exactly neutralize 2.21 grams of KHP ? ANSWER: mL potassium hydroxide

Consider the reaction Zn (s)  +  2 HCl (aq)  ---> ZnCl2  (aq)  +  H2 (g)  What volume (in milliliters)of 3.50M HCl is needed to completely react with 2.40 g of Zinc? Write your answer to three digits - for example 16.2 and leave of the mL term.  If your answer is a number like 18.0 it will show up as 18 in Canvas.

Given the following reaction equation. NaCl (aq) + Pb(NO3)2 (aq) NaNO3 (aq) + PbCl₂ (s) Calculate the mass of PbCl₂ produced when 12.00mL of 0.45M NaCl solution reacts. 3. Calculate the volume of a 0.85M NANO, solution needed to prepare 25.00 mL of 0.48M NANO, solution.

I keep getting this wrong .. help

You are a curious chemist, like Curious George (not Furious George). Therefore, you decide to find out the molar mass of an unknown solid that was dissolved in water. The unknown solution has a concentration of 0.495 M. You place 50.0 mL of the solution in a beaker and boil away the water. Afterward, 2.95 grams of solid remain in the beaker. What is the molar mass of the solid?

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. How many grams of KHP are needed to exactly neutralize 33.8 mL of a 0.459 M calcium hydroxide solution ?_______grams KHC8H4O4

?ClassID=1440190321 The US Department of Health recommends adding sodium fluoride to municipal drinking water to reduce tooth decay. The recommended amount is about 1.5 x 10-3 g NaF/L of water. What is the molarity of NaF in the drinking water? [NaF] = [? ]x 101 M Coefficient (green) Exponent (yellow) Enter

Transfer 0.5 mL phenolphthalein to the KHP, then transfer 12.2mL NaOH to the KHP that make it be pink. As the picture shows. Question: Write the molecular, total ionic and net ionic equations for this neutralization. Consider that  KHP (KHC6H4(COO)2) is a soluble salt that produces an ion which is a weak, monoprotic acid.
