Question

1. Convert 4 mL to µL. Show working.

2. Convert 400.0 nm to mm. Show working. Please provide an explanation as well.

Answer 1

4 mL is converted to 4000 µL by multiplying by 1000. To convert 400.0 nm to mm, divide by 10^6, resulting in 0.0004 mm.

Step-by-step explanation:

To convert 4 mL to µL, you can use the fact that 1 mL = 1000 µL. Therefore:

• 4 mL = 4 × 1000 µL
• 4 mL = 4000 µL

For converting 400.0 nm to mm, you need to know that 1 nm = 10-9 meters (m), and 1 mm = 10-3 meters. To convert nanometres to millimeters, you therefore divide by 106 (since 10-9 m / 10-3 m = 10-6):

• 400.0 nm = 400.0 × 10-9 m = 400.0 × 10-6 mm
• 400.0 nm = 0.0004 mm
