<u>Answer:</u> The mass of 97 % of NaOH solution required is 114.33 g
<u>Explanation:</u>
To calculate mass of a substance, we use the equation:
We are given:
Density of 10 % solution = 1.109 g/mL
Volume of 10% solution = 1 L = 1000 mL (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
The mass of 10 % solution is 1109 g.
To calculate the mass of concentrated solution, we use the equation:
where,
are the concentration and mass of concentrated solution.
are the concentration and mass of diluted solution.
We are given:
Putting values in above equation, we get:
Hence, the mass of 97 % of NaOH solution required is 114.33 g

Solubility is a property referring to the ability for a given substance to dissolve in a solvent
Periods are subdivided into eras by geologists.
The highly compressible state of a matter is its gaseous state. The gaseous molecules are highly compressible due to presence of maximum space between the molecules than the other state of the same material. As for example the gaseous form of water that is vapor has the maximum space between the H₂O molecules and lowest in the solid state that is ice.
The motion of the particle have some postulates which is called the kinetic theory of gas. The gaseous particles of any particular gas can move independently in the vessel in which it is kept. The motion of the gas in a vessel is described by the Brownian motion.
The gaseous state of the material like carbon di-oxide (CO₂), oxygen (O₂), nitrogen (N₂) remains nearest to the earth surface which is stratosphere.
