Answer:

[tex]concentration = \frac{0.15}{0.4}=0.375 mol/L[/tex]

Explanation:

Concentration: i is defined as the mole per litre.

[tex]concentration = \frac{mole}{volume in L}[/tex]

mole=0.15

volume=400 ml=0.4 litre

[tex]concentration = \frac{0.15}{0.4}=0.375 mol/L[/tex]

The concentration of a solution made with 0.150 moles of KOH in 400.0 mL of solution is 0.375M

HOW TO CALCULATE MOLARITY:

  • The molarity of a solution can be calculated using the following formula:

  • M = n/v

Where;

  1. M = molarity (M)
  2. n = number of moles (mol)
  3. v = volume (mL)

  • According to this question, 0.150 moles of KOH in 400.0 mL of solution is given. The molarity can be calculated as follows:

  • Volume = 400mL = 0.4L

  • Molarity = 0.150mol ÷ 0.4L

  • Molarity = 0.375M

  • Therefore, the concentration of a solution made with 0.150 moles of KOH in 400.0 mL of solution is 0.375M.
