DQ? Taken directly from PP3 slide 31
• Graduated cylinders shows
each line (scale) represents
1 ml increments.
• This instrument is accurate
to ones place, therefore
estimated digit should be in
tenth place.
• For scaled instruments the
estimated digit must be
determined by YOU.
• Liquid volume is 43.0 ml not
43 ml. The zero, in tenth
place, is the estimated digit.
