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.
