Answer:
Potassium compounds are quite common and are extremely useful for a variety of purposes. Potash and other potassium compounds have been used for centuries in the manufacture of glass products. Today 95% of the potassium compounds gathered in the world is used in the manufacture of fertilizers.
Potassium dichromate is an inorganic chemical compound possess immense industrial and laboratory importance. It is an orange crystalline solid with the chemical formula K2Cr2O7. It is a strong oxidizing agent and is soluble in water. It is used in the volumetric estimation of ferrous salts, iodides and sulphides for the preparation of chrome alum, chrome yellow and chrome red.
I would pick the shrimp because it has the most chromosomes so that is more protein we when you eat shrimp you are getting the most protein out of all of them

Answer:
Number of moles = 0.75 mol
Mass = 118.5 g
Explanation:
Given data:
Number of moles of KMnO₄ = ?
Mass in gram = ?
Molarity of KMnO₄ = 0.25 M
Volume of KMnO₄ solution = 3 dm³ (3 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles / L of solution
0.25 M = number of moles / 3 L
Number of moles = 0.25 M× 3 L
M = mol/L
Number of moles = 0.75 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 0.75 mol × 158 g/mol
Mass = 118.5 g
