Answer:
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
the prefix of the second word indicates that a molecule of carbon dioxide indicates that the compound contains two oxygen atoms

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.
