The equivalent volume of hydrogen at STP...

The equivalent volume of hydrogen at STP from one gram of a divalent metal when treated with a dilute mineral acid is 560 mL. Calculate the atomic mass of metal.

Text Solution

Verified by Experts

`"Metal" overset("acid")to"Hydrogen"`
560m of hydrogen = 1 g of metal
11200ml of hydrogen=?
Equivalent weight of metal `=(11200xx1)/(560)=20`
Valency of metal is 2
Atomic mass=Equivalent weight x valency
Atomic mass of metal `=20xx2=40`
