The specific heat is the amount of heat per unit mass required to raise the temperature to 1 degree Celsius. (This is from google)
Answer:
The molarity of a solution is 2.5 M
Explanation:
Molarity is a concentration unit that describes how much of a solution is dissolved in solution.
Molarity of a solution can found by using the formula,
Molarity (M) = (moles of solute)/(Liters of Solution).
Given, mass of Sodium = 114.95 grams.
Volume of water = 2 L.
Here, Sodium is solute as it is dissolved in water, which is the solvent.
Moles of Sodium(solute) can be found by using the formula,
Number of Moles = mass/Molecular weight.
mass of Sodium = 114.95 grams.
Molecular weight = 22.989 grams
Number of Moles of Sodium(solute) =114.95/22.989 = 5.
Substituting the values in the formula, we get,
M = 5/2 = 2.5 M
The name for NaCl is Sodium chloride
<h3>Salt and it's examples.</h3>
Salt is defined as the chemical compound that contains both a positively charged cation.and negatively charged anion.
It is formed by the reaction of acid and base is a neutralisation reaction.
Examples of salt include:
- Sodium Chloride or Common Salt (NaCl)
- Sodium Carbonate or Washing Soda (Na2CO3.10H2O)
- Baking Soda or Sodium Bi-carbonate (NaHCO3)
- Bleaching Powder or Calcium Hypochlorite.
Therefore another name for salt is common salt.

Avagadros number states that 1 mol of any substance is made of 6.022 x 10²³ units.
These units could be atoms that make up an element or molecules that make up a compound. CO₂ is a compound therefore its made of CO₂ molecules.
1 mol of CO₂ contains 6.022 x 10²³ molecules of CO₂
Therefore if 6.022 x 10²³ molecules of CO₂ make up 1 mol
then 1.25 x 10¹⁵ molecules of CO₂ make up -

Number of CO₂ moles present - 2.0756 x 10⁻⁹ mol of CO₂
