show all work and conversion steps

1) a hair 8 inches long. If the medulla is 60 % of the shaft and measures ~30 microns, what is the approximate total volume of the hair in m ^3?

2) it is needed 2.0 L HNO3 for your sample/test. If you have a micropipette with an outer diameter of 0.80mm and a wall thickness of 0.27 mm, to what height must you fill the capillary to obtain 2L?

3) Hexagon aquarium is filled up 10 cm from the table. Each side of the aquarium is 5.0 cm and the distance between 1 corner and the other directly across from it (going through the aquarium) is 10.0cm. The base of the base is 0.50 cm thick and the walls are 0.25cm thick. What is the volume of water contained in the aquarium?

4) 1.3g/cm^3 -> kg/mm^3

5) 1.5*10^-6kg/mm^3 -> g/ml

Explanation / Answer

4) 1 Kg = 1000g
Hence, 1.3 g = 1.3 / 1000 =.0013 Kg

1 cm3 = 10x10x10 mm3 = 1000 mm3

Hence 1.3 g/m3 = .0013/ 1000 kg/mm3 = 1.3x10-6 kg/mm3

5)

1 g/cm3 = 1 g/mL = 1000 kg/mm3.

1.5*10-6 kg/mm3= 1.5x10-6 x 1000g/mL or .0015 g/ml
