Answer:

Neither

Explanation:

Density is independent of size. Basically, the density of an object isn't determined by it's size.

If two objects are made of the same exact material, they will have the same exact density, regardless of the size.

So, the large brick and the small brick will have the same density, as long as they are made from the same type of brick material.

We know that Weighted atomic mass of Element is Calculated based upon their existence of isotopes and the Relative abundance of these isotopes.

Given that the Element X is Composed of :

Isotope                       Relative abundance                   Atomic Mass

⁵⁵X                                        70%                                               55

⁵⁶X                                        20%                                               56

⁵⁷X                                        10%                                                57

Weighted Atomic Mass of Element X :

= (0.70)(55) + (0.20)(56) + (0.10)(57)

= 38.50 + 11.2 + 5.70

= 55.4

So, the Weighted Atomic Mass of Element X is 55.4
