`8.6 g` of an element when treated with excess of acid produce 1900ml of `H_2` gas STP. The equivalent mass of metal is?

A

` 48.69`

B

` 58.69`

C

` 50.69`

D

`56.69`

Text Solution

Verified by Experts

The correct Answer is:
C
Equivalent mass ` = ("Mass of metal")/("voL of" H _(2) "gas at STP (litre)") = ( 8.6)/(1.9) xx 11.2 = 50.69`
