Answer: Set with equal densities are:
15.2 g copper and 50.0 g copper ; 11.2 g gold and 14.9 g gold
Explanation:
Density is defined as mass of the substance present in unit volume of the substance.
It is an intensive property which means that two different masses of same substance will have same value of density under same conditions.
So, from the given samples with equal density are:
- 15.2 g copper and 50.0 g copper will have the same value density.
- 11.2 g gold and 14.9 g gold will have the same value density.
Answer and Explanation:
The molar mass of a substance is all of the weights from the elements combined.
So, we have the elements
CU, S, and 
CU has a mass is 65
S mass is 32
O has a mass of 16, but there's 4 atoms of O, so we do 16 times 4, which is 64.
Now we add.
65 + 32 + 64 is 161.
<u>So, the answer is 160, or answer choice A.</u>

Isomer is defined as compounds with the same formula but different arrangement of atoms in its molecule and they differ in their properties. The <span>representation that can be used to show differences between isomers is the use of structural formula. It shows the arrangement of each atoms. It cant be molecular formula and 3D drawing because it does not show the arrangement of the atoms.</span><span>
