Unformatted text preview: in cm 3 . 6. a. Liquid hydrogen boils at –423 ° F. Express this temperature on the Kelvin scale. ( ° F= 1.8 x ° C+32, ° C= ( ° F32)/1.8, K= ° C+273.15) b. The melting point of a certain compound is –40 ° C. Express this temperature in ° F. 7. What is the volume of a cube in cm 3 that has an edge length of 0.010 m. (volume of a cube of side’a’ = a 3 ) 8. The average velocity of oxygen molecules at 1000 ° C is 8.0 x 10 4 cm/s. Express this in mi/h. ( 1 mi = 160.9 m, 1h = 60 min, 1min = 60s). 9. How many 325 mg aspirin tablets can be made from 32.5 kg of aspirin ? 10. A metal has a density of 4.55g/cm 3 . A sample of the metal has the shape of a cylinder with a circular crosssection. The cylinder is 7.55 cm long and has a mass of 153.20 g. Calculate the diameter of the cylinder (vol. of cylinder = ∏ r 2 h, ∏ = 3.14)...
