1.520 g of the hydroxide of a metal on ignition gave 0.995 g of oxide. The equivalent weight of metal is

Answer»

`1.520`
0.995
`19.00`
`9.00`

Solution :`("wt. of METAL HYDROXIDE")/("wt. of metal OXIDE") = (EM+ EOH^(-))/(EM + EO^(-))`
`:.(1.520)/(0.995) = (x+17)/(x+8)`
`:.1.520x+1.520xx8=0.995x+0.995xx17`
`:.1.520x+12.160=0.995x+16.915`
`:.0.525x=4.755`
`:.x=(4.755)/(0.525)= 9.057`
