how many nl are there in 70.6 μl?

Explanation:

Step1: Recall the conversion factor for cm to mm

1 cm = 10 mm

Step2: Convert 57.2 cm to mm

$57.2\times10 = 572$ mm

Step3: Recall the conversion factors for kg to g and g to cg

1 kg = 1000 g, 1 g= 100 cg, so 1 kg = 1000×100 = 100000 cg

Step4: Convert 0.0914 kg to cg

$0.0914\times100000=9140$ cg

Answer:

1. A. 572 mm
2. B. 9,140,000 cg
