determine the concentration of ferrous sulphate in mole/dm³ and gm/ dm³ using a standard potassium permanganate solution(.005m) 10 cm³ of ferrous solution,5cm³ of 5n h₂so4)

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
