The concentration of the Nitric acid solution : 0.114 M
<h3>Further explanation </h3>
Titration is a procedure for determining the concentration of a solution (analyte) by reacting with another solution whose known concentration (usually a standard solution) is called the titrant. Determination of the endpoint/equivalence point of the reaction can use indicators according to the appropriate pH range
Titrations can be acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases
Reaction
HNO₃ + NaOH → NaNO₃ + H₂O
Concentration a standard solution of sodium hydroxide : 0.0998 mol/dm³ , and the volume = 25 cm³
moles NaOH=

<em>From the equation, mol ratio HNO₃ : NaOH = 1 : 1, so mol HNO₃ = mol NaOH=</em><em>2.495 mlmoles</em>
<em></em>
The volume of HNO₃ = 21.8 cm³, so the concentration :

Yes but only if you're talking about treated apple juice with a naturally small amount of water mixed in.
The Correct Answer Is <span>Both Processes Produce Energy From Mass. </span>
If you mean how many electrons an atom contains then this is the same as the atomic number of the atom. For example, the atomic number of oxygen is 8 so it contains 8 protons. Since in a stable atom, the number of protons is equal to the number of electrons, oxygen contains 8 electrons.
If you have an ion and you want to know how many electrons it has lost or gained, you look at the charge. If it is a 2+ ion then it has lost two electrons, if it's a - ion then it has gained an electron. The number of electrons in an ion is the atomic number +/- the charge shown. For example a Mg2+ ion would have 10 electrons as a magnesium atom has 12 electrons and loses two to form the 2+ ion.
