I have been working on these but can't seem to figure them out? Could you please let me know the answer and the reasoning behind it? Thank you

Also if you have any suggesting for extra resources to help me in percentage yield and molarity, please let me know!

There are very similar versions of these questions, with a slight difference in values. Perhaps the working to these versions of the questions would assist you in solving your questions. They are as follows:

What is the percentage yield (no decimals in answer) where you obtained 6.8 grams from a reaction in which the theoretical yield was 25 g?

The working is as follows:

You dissolve 35.43 g of sodium chloride in 500 mL of water, what is the molarity of sodium cations in the solution as moles per litre?

The working is as follows:

I hope this helps! 😄
