Answer to Question #181276 in General Chemistry for Mel

Question

What is the percent yield if 14.0 grams of NaC𝑙(𝑠) is recovered from the reaction of 9.16 grams of C𝑙₂(𝑔) according to the reaction below?

2Na(s)+Cl2(g)—>2NaCl(s)

Answer 1

From the balanced equation

71g of Cl2 yields 2(58.5)g of NaCl

9.16g of Cl2 will yield

117.0/71 x 9.16= 15.09g

% yield = 9.16/15.09 x 100% = 60.7%
