Hydrogen-3 with scientific name Tritium often undergoes beta decay.
Answer:
Explanation:
% yields = <u>experimental yields</u> / theoretical yields )x 100%
=( 302 ÷ 320 )x 100% = 94.4 %
% error = 100% - 94.37% 5.64%
or u can use this law :
% error =(theoretical value - experimental value )/ theoretical value) x 100%
( 320 - 302 )/ 320 ) x 100% = 5.64%
