The equivalent mass is a pure number.When a known mass if element is changed into oxide directly or indirectly , the mass of oxide is noted.
MASS OF OXYGEN= Mass of oxide-mass of element Thus,
Eq mass=mass if element*8/mass of oxygen
MASS OF OXYGEN= Mass of oxide-mass of element Thus,
Eq mass=mass if element*8/mass of oxygen

My answer came out to be 32, but in book it's given 40.I don't know how
Let the total amount of oxide be 100
∴∴ mass of oxygen is 20
∴∴ mass of element is (100-20)=80
∴∴ equivalent mass of element=massofelementmassofoxygenmassofelementmassofoxygen×8×8
=8020=8020×8×8
=32=32
Hence you are correct....

I tried it online
Said i was correct for saying 32 and wrong with 40
ohk..thanks :)
