What volume error (in mL, round to the nearest tenth) would occur in the measuring of 4 mL of a liquid ingredient if the improperly calibrated measuring device created a 12 % error in all measurements?

Answer:

0.5 mL

Step-by-step explanation:

If the device wasn't properly calibrated, in volume the number can be estimated with a 3 rule:

100%------4mL

12%-------x=12*4/100=0.48≈0.5mL rounding to the nearest tenth
