Question

if you were asked to measure out approximately 5 ml of liquid, which lab instrument would you use? 100 ml graduated cylinder 10 ml graduated cylinder weigh boat test tube question 4 (1 point) if you weighed a substance on a balance and the balance ready 3.0106 g, what value would you report in your lab notebook? 3.010 g 3.0106 g 3.01 g 3 g

Explanation:

• For measuring approximately 5 mL of liquid, a 10 mL graduated cylinder is more appropriate than a 100 mL graduated cylinder (less precise for small volumes), a weigh boat (used for weighing, not measuring liquid volume), or a test tube (no precise volume markings).
• When reporting the mass from a balance, we report the value as read (3.0106 g) because that is the precision of the balance measurement. We don't round it to fewer decimal places unless instructed to do so for a specific reason (like significant - figure rules in a particular context, but here no such instruction is given).

Answer:

1. 10 mL Graduated Cylinder
2. 3.0106 g
