The concentration of HCl is equal to 2.54mol/L.
<h3>Mole calculation</h3>
To solve this question, one must use the molarity calculation, which corresponds to the following expression:
Thus, to find the molarity of the sample, the following calculations must be performed:
So, 0.00254 moles were added per 10ml, so we can do:
So, the concentration of HCl is equal to 2.54mol/L.

Answer:Types of Ions: ... Ionic Compounds Containing a Metal and a Polyatomic Ion 3. ... Molecular Masses from Chemical Formulas ... A cation is a positively charged ion; An anion is a negatively charged ion. ... for these ions are derived by naming the metal first, followed in parentheses by the charge written in Roman numerals.
I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.
Hope this helps!
50.0 mL of 0.500 M HCN and 25.0 mL of 0.500 M sodium hydroxide combination can be used to make a buffer with a pH of 4.2. The KK
an of benzoic acid, C6H5COOH, is 6.5×10-5 and the an of hydrocyanic acid, HCN, is 4.9×10-10.
Benzoic acid
A white (or colourless) solid with the chemical formula C6H5CO2H, benzoic acid is pronounced: "bnzo.k." The simplest aromatic carboxylic acid is this one. The term comes from gum benzoin, which was the substance's exclusive source for a very long period. Many plants naturally contain benzoic acid, which is used as an intermediary in the formation of numerous secondary metabolites[9]. Benzoic acid salts are employed as food preservatives. An essential starting point for the industrial synthesis of many other chemical compounds is benzoic acid. The term "benzoates" refers to the salts and esters of benzoic acid.
