The conductivity of a substance is the ability or power to conduct or transmit energy (in the form of heat, electricity, etc.) or waves (in the form of sound). It is measured in Siemens per meter.
An ion is not a particle within the atoms
%yield = 91.8
<h3>Further explanation</h3>
Given
20 g NaCl
45 g AgCl
Required
%yield
Solution
Reaction
NaCl + AgNO₃ ⇒ AgCl + NaNO₃
mol NaCl :
= mass : MW
= 20 g : 58,44 g/mol
= 0.342
mol AgCl from equation :
= 1/1 x mol NaCl
= 1/1 x 0.342
= 0.342
Mass AgCl(theoretical) :
= mol x MW
= 0.342 x 143,32 g/mol
= 49.02 g
%yield = (actual/theoretical) x 100%
%yield = (45/49.02) x 100%
%yield = 91.8
Your answer would be, I believe, The same number of decimal places as the least precise values!!!!
Hope that helps!!!
