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 900 times its own volume in hydrogen or deuterium gas at 1 atm and 273 K . Calculate the ratio of deuterium atoms to Pd atoms in a piece of fully saturated Pd metal. The density of Pd is $12.0 g / mL . (Pd = 106.4)$

If the ratio is $1 : x$ , the value of $x$ is.

Molar volume of D₂ at STP: 22.4 L. Moles D₂ = ( 900 m L /22400 m L / m o l ) = 0.04018 m o l . Moles Pd = ( 12 g /106.4 g / m o l ) = 0.1128 m o l . Ratio D:Pd = ( 2 × 0.04018 ) /0.1128 = 0.71 . So x = 1/0.71 = 1.4 .
