Answer:
The concentration of the magnesium fluoride solution is 0.0020 M
Explanation:
Step 1: Data given
Mass of MgF2 = 0.031 grams
volume = 250 mL = 0.250 L
Molar mass of MgF2 = 62.3 g/mol
Step 2: Calculate moles
Moles MgF2 = mass MgF2 / molar mass MgF2
Moles MgF2 = 0.031 grams / 62.3 g/mol
Moles MgF2 = 4.98 *10^-4 moles
Step 3: Calculate concentration of MgF2
Concentration MgF2 = moles MgF2 / volume
Concentration MgF2 = 4.98 *10^-4 / 0.250 L
Concentration = 0.0020 M
The concentration of the magnesium fluoride solution is 0.0020 M

Redox reaction has a great economic impact. many product that we use in our daily lives are made using redox reaction. some of which are electroplating, that we use in our watches. and redox reaction also caused the rusting of irons, so buildings will rust and become brittle
