12 g of an element combines with 32 g of oxygen. What is the equivalent weight of the element if the equivalent weight of oxygen is 8?

Text Solution

Verified by Experts

Suppose the element is M.
No. of eq. of `M =` no. of eq. of O
`("wt. of M")/(E_M) = ("wt. of oxygen")/( E_O)`
`(12)/( E_M) = ( 32)/( 8) `
`E_M = ( 12 xx 8)/( 32) = 3`.
