Question

Making a gold solution is very difficult but it can be done. Gold as we know it, the yellow shinny stuff, can be dissolved in water when NaCN is also dissolved in the same water. How many liters of 0.005M gold solution can be prepared by using 0.01 moles of gold?

Answer 1

To determine the volume of a 0.005M gold solution that can be made with 0.01 moles of gold, the molarity equation is rearranged to solve for volume, resulting in 2 liters of solution.

Step-by-step explanation:

The question asks how many liters of a 0.005M gold solution can be prepared using 0.01 moles of gold. To find the volume of the solution that can be made with the given moles of gold, we can use the formula for molarity:

Molarity (M) = moles of solute (mol) / volume of solution (L)

Rearranging the formula to solve for the volume gives:

Volume (L) = moles of solute (mol) / Molarity (M)

Substituting the given values:

Volume (L) = 0.01 mol / 0.005 M

Volume (L) = 2 L

Therefore, you can prepare 2 liters of a 0.005M gold solution using 0.01 moles of gold.
