Answer:
20 grams
Explanation:
Equivalent weight is the quantity of an element that will exactly react with 1g of Hydrogen or 8 grams of Oxygen.
Now for the given substance we have 40 grams which completely reacts with 2 grams of hydrogen so considering the reaction to be in direct proportion, 1 gram of hydrogen will then utitlise 20 grams ( half of 40). So we can say that equivalent weight of metal is 20 grams
