The concentration of the sodium hydroxide solution in mol/l is 0.176 M.
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
Given
V =25 ml = 0.025 L
M = 0.1
C₁ = 0.1
V₁ = 21.50 = 0.022 L
C₂ = ?
V₂ = 25 ml = 0.025 L
C₁V₁ = C₂V₂
C₂ = C₁V₁ / V₂
= 0.1 * 0.022 * 2 / 0.025
= 0.176 M
The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.

Charles law gives the relationship between temperature of gas and volume of gas.
It states that for a fixed amount of gas, temperature is directly proportional to volume of gas.
V / T = k
where V- volume , T - temperature and k - constant
![\frac{V1}{T1} = \frac{V2}{T2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BV1%7D%7BT1%7D%20%3D%20%20%5Cfrac%7BV2%7D%7BT2%7D%20)
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation.
T1 = 250 °C + 273 = 523 K
T2 = 150 °C + 273 = 423 K
Substituting the values in the equation,
![\frac{310 mL}{523 K} = \frac{V}{423K}](https://tex.z-dn.net/?f=%20%5Cfrac%7B310%20mL%7D%7B523%20K%7D%20%3D%20%20%5Cfrac%7BV%7D%7B423K%7D%20)
V = 251 mL
the new volume is 251 mL
the answer is c
Explanation:
because c has all elements mixed together
