1.0 g of Ca and 1.63 g of a metal M when treated with an acid in excess separately, produce the same amount of hydrogen. If equivalent weight of Ca is 20.0, what is the equivalent weight of metal M?

Options

A. `12.3`
B. `16.3`
C. `32.6`
D. `65.2`

Answer

C

Explanation

Equal number of equivalents produce the same amount of hydrogen.
`( 1.0 )/(20.0 ) = ( 1.63 )/( "Equivalent weight of M ")`
Equivalent weight of M=`(1.63 xx 20 )/( 1.0 ) = 32.6`
