Question

in problems 1 through 4, identify the type of syringe shown in the figure. place an arrow at the appropriate level of measurement on the syringe for the volume given.

1. syringe: 0.68 ml
2. syringe: 5.6 ml
3. syringe: 1.8 ml
4. syringe: 3.2 ml

Explanation:

Problem 1: Syringe with 0.68 mL

Step1: Identify syringe type (1 mL syringe, markings 0.1 to 1.0 mL, each major mark 0.1 mL, minor marks likely 0.02 mL? Wait, 0.68: 0.6 + 0.08. Wait, 0.1 mL major, so between 0.6 and 0.7: 0.68 is 0.6 + 0.08. If each minor division is 0.02 mL (since 0.1 / 5 = 0.02), then 0.6 + (4*0.02) = 0.68. So arrow at 0.68 mark.

Step2: Type: 1 mL syringe (capacity up to 1.0 mL).

Step1: Syringe type: 12 mL syringe (markings 1 - 12 mL). Major marks 1 mL, minor marks: between 1 - 2, how many? Let's see, 5.6: 5 + 0.6. If each major (1 mL) has 10 minor divisions, each minor is 0.1 mL. So 5.6 is 5 mL + 6 minor divisions (0.6 mL). So arrow at 5.6 (6th minor above 5).

Step2: Type: 12 mL syringe.

Step1: Syringe type: 3 mL syringe (markings 1/2, 1, 1 1/2, 2, 2 1/2, 3 mL). Let's check divisions: between 1 and 2, how many? 1.8: 1 + 0.8. If between 1 and 2, there are 10 minor divisions (each 0.1 mL), then 1.8 is 1 + 8 minor divisions. So arrow at 1.8 (8 minor above 1).

Step2: Type: 3 mL syringe.

Answer:

Type: 1 mL syringe; Arrow at 0.68 mL mark (between 0.6 and 0.7, 4 minor divisions above 0.6 if each minor is 0.02).

Problem 2: Syringe with 5.6 mL
