Calculate the volume of a 1.25 M solution of HCN made from 31 grams of HCN

V HCNsln = 0.9176 L

Explanation:

V HCNsln = ?

∴ m HCN = 31 g

∴ C HCNsln = 1.25 mol/L

∴ molar mass HCN = 27.0253 g/mol

⇒ V HCNsln = (31 g)*(mol/27.0253 g)*(L/1.25 mol) = 0.9176 Lsln

The best and most correct answer among the choices provided by your question is the second choice or letter B which states that "A metal atom forms a cation, and a nonmetal atom forms an anion."

Ionic bonding can result from a redox reaction when atoms of an element (usually metal), whose ionization energy is low, give some of their electrons to achieve a stable electron configuration. In doing so, cations are formed.
