<h3>Explanation </h3> + 2 e⁻ →
It takes two moles of electrons to reduce one mole of cobalt (II) ions and deposit one mole of cobalt.
Cobalt has an atomic mass of 58.933 g/mol. 0.500 grams of Co contains of Co atoms. It would take
of electrons to reduce cobalt (II) ions and produce the
of cobalt atoms.
Refer to the Faraday's constant, each mole of electrons has a charge of around 96 485 columbs. The 0.01697 mol of electrons will have a charge of . A current of 0.961 A delivers 0.961 C of charge in one single second. It will take
to transfer all these charge and deposit 0.500 g of Co.
Answer : The volume given to the patient should be, 85.5 mL
Explanation :
As we are given that the suspension contains 10g/15mL.
Now we have to determine the volume should be given to the patient.
As, 10 grams of lactulose syrup needed 15 mL volume of solution
So, 57 grams of lactulose syrup needed volume of solution
Thus, the volume given to the patient should be, 85.5 mL
