same mass of copper, is :

(A) 1 : 2 (B) 1 : 1 (C) 2 : 1 (D) none of these​

Answer 1

The correct answer is C) 2 : 1.

Explanation:

• Mass is a term used in Chemistry.

• This term is used to define the weight of any shapeless matter.

• It is specifically used to define the role played by the weight of atoms or molecules in various elements and compounds.

• Different ratios of oxygen in different elements affect the composition and nature of the material.

Answer 2
