calculate the concentration for the reaction of 0.25mole 0f sodium hydroxide NaOH and water H20 solution of 250cm^3. Provide the answer in cubuc decimeter
To calculate the concentration of the sodium hydroxide solution in cubic decimeters (dm^3), we need to convert the volume of the solution from cm^3 to dm^3.
Given:
- Amount of sodium hydroxide (NaOH) = 0.25 moles
- Volume of the solution = 250 cm^3
Step 1: Convert cm^3 to dm^3
To convert cm^3 to dm^3, divide the volume by 1000.
250 cm^3 = 250/1000 dm^3 = 0.25 dm^3
Step 2: Calculate the concentration (in moles per dm^3)
Concentration (mol/dm^3) = Amount of solute (in moles) / Volume of solution (in dm^3)
Concentration of NaOH = 0.25 moles / 0.25 dm^3 = 1 mol/dm^3
Therefore, the concentration of the sodium hydroxide solution is 1 mol/dm^3.
