Ave=0.97986
CF= -0.020140/mL
True volume ung mass ng water/density Correction factor per mL= true volume/volume from buretCF=ave-1 If ave1
Bale sabi ng average imbes na 1mL ang makuha mo every withdraw, 0.97986 lang nakukuha mo kaya may correction factor ka na negative tas minus mo sa 1 bale 0.020140
Example 1. Ave= 0.98 CF= -0.02mL1. Nagtitrate ka nabasa mo 4mLCorrected volume= 4mL-(CFx4mL)= 4mL-(0.02x4)=3.92mL (tama to na di dapat mas Malaki sa 4mL ung corrected volume mo kasi nga per mL mo butal ng 0.02 orayt rock and roll to the world) Example 2. Ave= 1.05 CF= +0.05mL1. Nagitrate ka nabasa mo 25.5mLCorrected volume= 25.5+(25.5x.05)= 25.5+ (25.5x0.05)=26.775mL ( tama din to na di dapat mas maliit sa 25.5 ung corrected volume mo kasi nga ung per mL mo mas Malaki sa 1mL haha orayt again rock and rowl to the world.
