"14 g" Your strategy here will be to use the volume of the reaction vessel and the number of moles of carbon monoxide, "CO", to calculate the initial concentration of the reactant. Once …

6.2 * 10^(-4) The idea here is that you can find the equilibrium concentration of atomic bromine, "Br", by using the percent of molecular bromine, "Br"_2, that gets converted by the reaction. …

The acid in excess is then titrated with N aOH (aq) of KNOWN concentration....we can thus get back to the concentration or molar quantity of M (OH)2...as it stands the question (and answer) …

We can find the concentration of H + or H 3O+ by three ways One is by the ICE table (but this is a 5% rule) and the other is square root which is absolutely correct and the other is Ostwald's law …

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 …

Note that we lost a solution of #x = "2.69 M"#, but that's OK because it is nonphysical; #2.000 - x# would have given a negative concentration for the reactants.

Apr 7, 2017 · Here's what I got. Silver thiocyanate is insoluble in water, which implies that a dissociation equilibrium is established when this salt is dissolved in water. "AgCNS"_ ((s)) …

In order to find the diluted solution's mass by volume percent concentration, you must determine how many grams of solute you have in "100 mL" of solution.

Use an ICE table to find the concentration of the hydroxide ions - all the species are in aqueous solution (except water), so I won't add the states for simplicity

Since you are given the concentration of hydroxide [OH-] = #1 x 10 ^ (-4)# M you can calculate that the pOH is 4 by taking the negative log of the [OH-] concentration. Since pOH = 4, the pH …
