Answer 1

To calculate the percent yield for a chemical reaction, you need to know the theoretical yield and the actual yield of the product.

The percent yield is calculated using the following formula:

% yield = (actual yield / theoretical yield) x 100

In this case, the theoretical yield is 5.3 g and the actual yield is 4.00551 g.

So, the percent yield is:

% yield = (4.00551 g / 5.3 g) x 100 = 75.59 %

Therefore, the percent yield for the chemical reaction is 75.59%.

It's important to note that percent yield is a measure of the efficiency of a chemical reaction, it is the ratio of the actual yield of product to the theoretical yield, multiplied by 100. The theoretical yield is calculated from the stoichiometry of the balanced equation for the reaction, and the actual yield is the amount of product obtained in the laboratory. A yield of 100% indicates that all the reactant has been converted to product, while a yield less than 100% means that some of the reactant has been lost or wasted, and a yield greater than 100% is not possible in real chemistry.
