Explanation:
Because gold is a very unreactive metal and exists as a pure substance (instead of oxides).

Hello there!
In this case, in agreement to the given chemical reaction, it is possible for us to calculate the mass of NH3 required to remove 57.0 g NO via the stoichiometry based off the 4:6 mole ratio between them:
Best regards!
Answer:
A. Yes, Amanda find the number of moles of NaCl correctly.
B. 0.73 M.
Explanation:
<em>A. Did Amanda find the number of moles of NaCl correctly? If not, explain.
</em>
-
Yes, Amanda find the number of moles of NaCl correctly.
- The relation to find the no. of moles of NaCl is:
<em>No. of moles (n) of NaCl = mass/molar mass.</em>
mass of NaCl = 32.0 g, molar mass of NaCl = 58.45 g/mol.
∴ No. of moles (n) of NaCl = mass/molar mass = (32.0 g)/(58.45 g/mol) = (32.0 g NaCl)*(1 mol of NaCl)/(58.45 g NaCl) = 0.547 mol ≅ 0.55 mol.
<em>B. What does Amanda need to do next to calculate the molarity of the NaCl solution? Show your work for full credit.</em>
<em></em>
- Molarity is the no. of moles of solute dissolved in a 1.0 liter of a solution.
∴ M = (no. of moles of NaCl)/(volume of solution (L)) = (0.55 mol)/(0.75 L) = 0.73 M.

<h3>
What are the properties of Saturated solution ?</h3>
A saturated solution is one that contains all of the solute that can possibly dissolve in it. The most sodium chloride that may dissolve in 
of water at 
°C is 
. Past that point, adding more 
won't cause it to dissolve because the solution is already saturated.
The solution reaches a point when it is saturated. This indicates that if you add more of the substance, it will stop dissolving and instead stay solid. The amount depends on how the solvent and solute interact molecularly.
