Mole Concept and Stoichiometry..Numerical 05
In a silver-plating system, an electrolysis current of 5.0 A is used for a certain time and 0.5 moles of silver is deposited. How many moles of copper and iron will be deposited in their respective plating system if an electrolysis current of 10.0 A is passed for twice the..
Atoms and Nuclei Problems - Numerical 12
12. - The half-life of 92 U 238 against alpha decay is 4.5 x 109 years. How many disintegrations per second occur in 1 g of 92 U 238 ? Suggested solution: Again, since one k mole of any isotope contains Avogadro's number of atoms, there fore 1 g of 92 U 238 contains Half life T = 4.5 10 9..
