1. 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.
