The molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.
<h3>How to calculate molarity?</h3>
The molarity of a solution can be calculated by dividing the number of moles of the solute by the volume of the solution as follows:
Molarity = no of moles ÷ volume
According to this question, a solution has 26 moles of NaCl in 2. 7 l of water. The molarity is as follows:
Molarity = 26mol ÷ 2.7L
Molarity = 9.6M.
Therefore, the molarity of a solution that has 26 moles of NaCl in 2.7L of water is 9.63M.

Answer: -
Chemical formula of sodium hydroxide = NaOH
Chemical formula of Nickel (II) Chloride = NiCl₂
The product is a solid compound of Ni²⁺ ions and hydroxide ions.
So the compound formed is Nickel (II) Hydroxide.
Chemical formula of Nickel (II) Hydroxide = Ni(OH)₂.
Since a double displacement reaction occurs, the other product should be NaCl.
The balanced chemical molecular equation for the reaction is thus
NiCl₂ + NaOH → Ni(OH)₂ + NaCl.
