Answer:
It would become more neutral when diluted
Explanation:
Assuming you dilute it with water, the more diluted the substance, the more neutral (and closer to 7), it would be. Ie straight lemon juice is more acidic than lemonade, which is more acidic than water. I hope this helps :)
Mass of NaCl : 5.85 g
<h3>Further explanation</h3>
Given
5.3 g Sodium carbonate (Na₂CO₃)
Required
Mass of NaCl
Solution
Reaction
Na₂CO₃ + 2HCl ⇒ 2NaCl + H₂O + CO₂
mol of Na₂CO₃ (MW=106 g/mol) :
= mass : MW
= 5.3 g : 106 g/mol
= 0.05
From the equation, mol ratio Na₂CO₃ : NaCl = 1 : 2, so mol NaCl :
= 2/1 x mol Na₂CO₃
= 2/1 x 0.05
= 0.1
Mass of NaCl (MW=58.5 g/mol) :
= mol x MW
= 0.1 x 58.5
= 5.85 g

Explanation:
Answer:
The molarity of the solution is 0.29
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
Molarity is expressed in units .
In this case:
- number of moles of solute= 2.1 moles
- volume= 7.3 liters
Replacing:
Molarity= 0.29
<u><em>The molarity of the solution is 0.29 </em></u><u><em></em></u>
Precision can be defined as the
<span>reproducibility of a measured value.

Precision is how close the measured values are to each others. In contrast with accuracy, accuracy is the </span><span>agreement between a measured value and an accepted value. Accurate data are always precise while precise data is not always accurate.</span>
