Answer:
Mass percentage of analyte = 0.10%
Explanation:
The mass of analyte in the solution is calculated as follows:
n = CV = (21.1 mgL⁻¹)(100 mL)(1L/1000mL) = 2.11 mg
The mass percentage of the analyte is calculated as follows:
(g analyte)/(g sample) x 100%
(2.11 mg)(1g/1000g) / (2.05g) x 100% = 0.10%
Answer:
Strong acids contain more A− than weak acids do.
Strong acids contain more H3O+ than weak acids do
Explanation:
When we talk about a strong acid, we are referring to any acid that is completely dissociated or ionized when it is in an aqueous solution.
It is very eager to lose a proton, H+ in solution according Arrhenius definition.
In aqueous solution, a strong acid ionizes as follows:
HA(aq) + H2O → H3O+(aq) + A−(aq)
Since, strong acids ionize completely in solution, strong acids contain a greater H3O+ and A− concentration than solutions of weak acids.

Answer:
2.475 mol of O2 formed.
Explanation:
Given 1.65 moles of KClO3 as the target amount in the reactant, used the coefficient of the balanced chemical reaction involved to determine the number of moles of O2 molecules formed.
x mole of O2 = 1.65 mol KClO3 x [(3 mol O2)/ (2 mol KClO3)] = 2.475 mol of O2
x mole of O2 formed = 2.475 mol of O2
