Na2O H2 --> 2Na H2O A student performed the above reaction in the lab, and obtained an actual yield of 3.9 grams of H2O. He calculated a theoretical value of 4.2 grams of H2O. Calculate the percent yield of the reaction.

Percentage yield = 92.86%

Explanation:

We are given;

Actual yield = 3.9 grams

Theoretical yield = 4.2 grams

Formula for percent yield is;

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

Thus;

% yield = (3.9/4.2) × 100%

% yield = 92.86%

answer: h+ its less than oh
