1.Determine the percent composition of Lithium nitrate.
You want percent Li in LiNO3, perdent N in LiNO3 and percent O in LiNO3. This is just like % anything; i.e., it's (grams Li/grams LiNO3)*100 = ?
%Li = (atomic mass Li/molar mass LiNO3)*100 = ?
%O = (3*atomic mass O/molar mass LiNO3)*100 = ?
%N = (atomic mass N/molar mass LiNO3)*100 = ?
2. Indicate whether each of the following compounds acts as an electrolyte when dissolved In water
a) sulfiric acid I assume you meant sulfuric acid
b) ethanol
c) glucose
d) sodium nitrate
Do you know which ones are ionic and which are covalent compounds? Ionic compounds dissolve in water and the ions conduct electricity; therefore, they are electrolytes. Covalently bonded compounds dissolve in water but they do not break apart into ions; therefore, they are non-electrolytes in solution. Solutions of a and d are electrolytes.
