To find the molar concentration of the HCl solution, we can use the equation:
M1V1 = M2V2
Where:
M1 = molar concentration of HCl
V1 = volume of HCl solution
M2 = molar concentration of Mg(OH)2
V2 = volume of Mg(OH)2 solution
Plugging in the values:
M1 * 50.0 mL = 0.150 M * 185.0 mL
M1 = (0.150 M * 185.0 mL) / 50.0 mL
M1 = 0.555 M
Therefore, the molar concentration of the hydrochloric acid (HCl) solution is 0.555 M.
M1V1 = M2V2
Where:
M1 = molar concentration of HCl
V1 = volume of HCl solution
M2 = molar concentration of Mg(OH)2
V2 = volume of Mg(OH)2 solution
Plugging in the values:
M1 * 50.0 mL = 0.150 M * 185.0 mL
M1 = (0.150 M * 185.0 mL) / 50.0 mL
M1 = 0.555 M
Therefore, the molar concentration of the hydrochloric acid (HCl) solution is 0.555 M.
