A metal oxide reacts with water to produce a metal hydroxide. What additional information would you need to determine the percent yield of metal hydroxide from this reaction?

theoretical yield and actual yield.

Instead of theoretical yield, if you knew the name of the metal, an equation could be written and the theoretical yield could be calculated.

Thanks! And can you calculate the percent yield if they don't give the actual yield?

No. Unless they give some data that would allow you to calculate actual yield; such as, so much was obtained under different conditions, things like that.

K thanks

To determine the percent yield of the metal hydroxide from this reaction, you would need the following additional information:

1. Balanced chemical equation: The balanced chemical equation represents the stoichiometry of the reaction. It tells you the molar ratio between the metal oxide and the metal hydroxide. This information is crucial for determining the theoretical yield of the metal hydroxide.

2. Mass or moles of the metal oxide: You need to know either the mass or the number of moles of the metal oxide used in the reaction. This information helps determine the amount of metal hydroxide that could potentially be produced if the reaction goes to completion.

3. Actual yield of the metal hydroxide: The actual yield is the amount of metal hydroxide that is obtained experimentally. This can be determined by measuring the mass of the metal hydroxide produced or by other means of analysis.

With these pieces of information, you can calculate the percent yield of the metal hydroxide using the following formula:

Percent Yield = (Actual Yield / Theoretical Yield) x 100

The theoretical yield is calculated based on the stoichiometry of the balanced chemical equation, while the actual yield is obtained from experimental data.
