How to calculate the molarity of a solution In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the number of moles of the acid being neutralized. ...
Calculate the pH of a buffer with different moles of a weak acid and conjugate base: 0.010 L of 0.10 M acetic acid, and 0.015 L of 0.10 M CH_{3}COONa . You need to produce a buffer with pH of 5.75. You have a solution with 30.0 g of acetic acid (pKa = 4.75). How many m...
in a 100 mL sample of water that took 50 drops of hydrochloric acid to neutralize, divide 50 by 20,000, to get 0.0025 L, multiply 0.0025 by 5 to get 0.0125 moles, convert it to 0.0125 equivalents, dividing 0.0125 by 0.1L to get 0.125, then taking the...
Chemists sometimes use titration to determine the alkalinity of an unknown substance. The term "alkalinity" refers to the degree to which a substance is basic—the opposite of acidic. To titrate, you add a substance with a known [H+] concentration—or pH—to the unknown solution one drop at...
Given 2 grams of Cu(NO3)2 and excess NaOH, calculate how much Cu(OH)2 can be produced? The molar mass of NaOH is 40g/mol, how many grams of NaOH are required to yield 0.65 mol? How many moles of H2O are produced when ...

How many moles of CaCO3 are present in 30.6 g? Molar Mass: The molar mass is a ratio of the mass per mole of a certain compound or element. This allows us to acquire the number of moles given the mass of a substance, and vice versa. The molar mass is an intrinsic property, which...
Then, by using the molar ratio between KHP and NaOH (1:1), we can calculate the moles of NaOH used. Finally, by dividing the moles of NaOH by the volume of base used, we can calculate the concentration of the base. 3. To determine the moles of HCl needed to neutralize the given ...
To solve the problem of how much charge (in Faraday) must flow through a solution during the electrolysis of aqueous Na₂SO₄ to produce 33.6 L of product gases at 50% current efficiency, we can follow these steps:Step 1: Understand
Answer to: 100 mL of a 0.1 M solution of NaOH is neutralized to pH 7 with H2SO4. How many grams of H2SO4 are required to achieve this...
