Question

Recent controversial efforts to generate energy via 'cold fusion' of deuterium atoms have centred on the remarkable ability of palladium metal to absorb as much as 1120 times its own volume of deuterium gas at 1 atm and 0 ∘ C . The number of deuterium atoms per 10 atoms of Pd in a piece of fully saturated Pd metal is (Density of Pd = 11.8 g / ml and atomic mass of Pd = 106.2 )

Question Explanation: Calculating the volume of gas produced from a known mass of reactant. Concept: Mole Concept and Stoichiometry

Solution: One mole of carbon reacts with oxygen to produce one mole of carbon dioxide. At N.T.P, one mole of any gas occupies a volume of 22.4 L . We first find the moles of carbon used and then multiply by the molar volume.

$\frac{N _{D}}{N _{Pd}} = \frac{( \frac{1120 V}{22400} \times N _{A} ) \times 2}{( \frac{V \times 11.8}{106.2} \times N _{A} )} = \frac{9}{10}$

Final answer: 9.00
