When monovalent cation (X) binds to divalent anion (Y) it will form
Romashka-Z-Leto [24]

When a monovalent cation X binds to a divalent anion Y, a compound with the formula X_2Y would be formed.

A monovalent cation is an atom that has lost an electron. Hence, such cation has a single positive charge. A monovalent cation X will, thus, be X^+

A divalent anion is an atom that has gained two electrons. Such anion has 2 negative charge. Thus, divalent Y would be Y^2^-

Since Y is a divalent anion, it requires 2 electrons in order to successfully bind with another charged atom, a cation to be specific. Thus, two of  X^+ would be required to successfully bind  Y^2^-

   Y^2^- + X^+ + X^+ ----> X_2Y

21) What is the mass of 5.22 moles of Na 2 CO 3
german

Answer:

5.22 moles of Na₂CO₃ have mass of 553.22 g

Explanation:

Given data:

Mass of Na₂CO₃ = ?

Number of moles of Na₂CO₃ = 5.22 mol

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of Na₂CO₃ = 105.98 g/mol

Mass = 5.22 mol  ×  105.98 g/mol

Mass = 553.22 g

Thus, 5.22 moles of Na₂CO₃ have mass of 553.22 g.
