How do you calculate the osmolarity of a #6.0 * 10^-2# M NaCl solution? How come a raisin placed in a cup of pure water overnight will puff up with water, in terms of osmosis? How does chloride ion …

Since both #"HA"# and #"A"^"-"# are in the same solution, the ratio of their moles is the same as the ratio of their molarities. We can use the Henderson-Hasselbalch equation to calculate the #"pH"#.

Now we can calculate the hypotenuse #g# using Pythagorean theorem:

Calculate the molarity of the ammonia in the dilute solution If 3.0 % of the ammonia reacts. its concentration decreases by 0.03 × "0.0173 mol/L = 0.002 18 mol/L" ∴ c = " (0.0173 - 0.0022) mol/L = …

As you know, molarity is a measure of the number of moles of solute, which in your case would be phosphoric acid, present in

Use Hess's Law and the following information to calculate the change in enthalpy for the reaction 2C + H2 -> C2H2? How do you use Hess's law to find the enthalpy of reaction for these reactions?

You use the standard enthalpies of formation. To calculate the enthalpy change for a reaction, in your case for the combustion of ethane, you can use the standard enthalpies of formation of the species …

Mar 26, 2016 · ΔG= "-9.35 kJ/mol" > We must calculate the equilibrium constant for the reaction, then calculate the free energy change.

Calculate the concentration of the original protein This comes from Beer's Law: A = εcl, where A is the absorbance, ε is the extinction coefficient, c is the concentration, and l is the path length. For …

If you want to calculate mass concentration, divide the mass of the solute #m# by the volume of solution #V#. #ρ=m/V# Your answer is wrong because you used the volume of solvent instead of solution. …
