Answer:The molar mass is the mass of a given chemical element or chemical compound (g) divided by the amount of substance (mol).
The molar mass of a compound can be calculated by adding the standard atomic masses (in g/mol) of the constituent atoms.

Explanation:
It could be Nitrous oxide
The required amount of KClO₃ to prepare a saturated solution is 48 grams.
<h3>What is solubility?</h3>
The ability of a material, the solute, to create a solution with another substance, the solvent, is known as solubility.
Given graph is plotted between the temperature and solubility of the substance at 100g of water, so for the given points calculation will be:
- According to the graph for the KClO₃ we require almost 48g of KClO₃ to prepare a saturated solution.
- From the graph it is clear that at 40°C 40g of KCl will dissolve in 100g of water then amount of KCl which will dissolve in 68g of water will be calculated as:
x = (40)(68) / (100) = 27.2g
- On the basis of the graph, if 75 grams of calcium chloride is added to 100 g of water at 25°C then the obtained solution is the unsaturated as they have les solute then the limit.
- Based on the graph cerium sulfate behaves like a precipitate which will not dissolve at any temperature and present in the physical state.
- We can add more 30g to make the KCl solution saturated.
Hence, we require almost 48g of KClO₃ to prepare a saturated solution of KClO₃.

There are more reactants than the products
Explanation:
For any system in equilibrium, the molar concentration of all the species on the right hand side is related to the molar concentrations of those at the left hand side by a constant known as the equilibrium constant (K
).
The constant is temperature dependent.
- When the equilibrium constant is less than 1, it implies that there are more reactants than the products.
- If the constant is equal to 1, the products and reactants are the same.
- If the constant is greater than 1, the products are more than the reactants.
