Answer:
3. 9.2 mL; 4. 0.25 mL
Explanation:
3. 12 mL syringe
The arrow points to the first division between 9 mL and 10 mL.
There are five divisions, so
5 divisions = 1.0 mL or
1 division = 0.2 mL
The reading is
9.0 mL + 0.2 mL = 9.2 mL
4. 0.5 mL syringe
The arrow points to the fifth division between 0.20 mL and 0.30 mL.
There are 10 divisions, so
10 divisions = 0.10 mL or
1 division = 0.01 mL
5 divisions = 0.05 mL
The reading is
0.20 mL + 0.05 mL = 0.25 mL
