<h3>
The Law of Conservation of Mass</h3>
<em>Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.</em>
<em>The Law of Conservation of Matter also states that the matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.</em>

Answer:
249.01 g/mol
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
Explanation:
<u>Step 1: Define</u>
Au(CN)₂
<u>Step 2: Identify</u>
Molar Mass of Au - 196.97 g/mol
Molar Mass of C - 12.01 g/mol
Molar Mass of N - 14.01 g/mol
<u>Step 3: Find MM</u>
Molar Mass of Au(CN)₂ - 196.97 + 2(12.01) + 2(14.01) = 249.01 g/mol
The answer is D or 4,3,2!
The first question it would would release the same amount.the answer to the second question would be the experimental group.
