If a titration of 0.5533 grams of KHP needs 25.84 mL of a NaOH solution to reach the equivalence point, what is the concentration of the NaOH? How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to r...
Determine the energy change for the following reaction. Indicate if it is endothermic or exothermic. {eq}H_2 + Cl_2 \rightarrow 2HCl {/eq} Enthalpy of Reaction: The enthalpy of a reaction can be used to determine whether the chemical reaction...
While it is important to understand moles and the number of atoms and molecules, a more practical unit for experiments is the gram, which is a unit of mass. You cannot measure a mole of a substance in a laboratory, but you can measure its mass in grams on a balance. The conversion fa...
Calculate the concentration of hydrogen ions in an acetic acid solution given that the pKa = 4.76 and the ratio of [CH_3 COO^- ]/[CH_3 COOH] is 0.6. Break down the mathematical steps when you get ''4.53 = -\log(H^+)'' and the steps to the final answer of Calculate the Ka...
