Question

how many decimal places are used when recording the volume​

Answer 1

10 ml since there are 20 decimal places in a speaker soun

Answer 2

The 10-mL graduated cylinders are always read to 2 decimal places (e.g. 5.50 mL) and the 100-mL graduated cylinders are always read to 1 decimal place (e.g. 50.5 mL). so that the line at the bottom of the meniscus gives the most accurate reading.
