Trial 4: 
 34.4mL-26.2mL= 8.2mL 
 (8.2/1000)/(10mL/1000)= 0.82M 
 Trial 5: 
 42.65mL-34.4mL= 8.25M 
 (8.25mL/1000)/(10mL/1000)= 0.825M 
 Trial 6: 
 44.6mL-36.65mL= 7.95mL 
 (7.95mL/1000)/(10mL/1000)= 0.795M 
 Average Molarity: 
 (0.89M+0.81M+0.82M+0.82M+0.825M+0.795M)6= 0.842M 
 % Deviation: 
 (0.825-0.810)/0.842*100= 1.78%
