      So, density can be used to determine the identity of a substance. Question: The mass of an object is 15 grams. Its volume is 10 milliliters. What is its density? Density = mass / volume = 15 grams / 10 milliliters = 1.5 gm/ml. Density is also useful in determining if an object will float on water. The density of water is approximately 1 gram/ml.

      From the solution to Problem W3.46, planar densities for FCC (100) and (111) planes are and , respectively—that is and (where R is the atomic radius). Thus, since the planar density for (111) is greater, it will have the lower surface energy.

      10) In chemistry, the pH of an aqueous solution is a measure of its acidity. The pH scale ranges from 0 to 14, inclusive. A solution with a pH of 7 is said to be neutral, a solution with a pH greater than 7 is basic, and a solution with a pH less than 7 is acidic.

      (1) Stain the smear with crystal violet solution for 1 minute: then wash with water for a few seconds. Drain off excess water on paper toweling and blot gently. (2) Apply Gram's iodine solution for 1 minute; wash with water, drain and blot. (3) Decolorize with alcohol (95%) until free color has been washed off (approximately 30 seconds).

      Beyond the ‘established’ new frontier of mmWave bands, the upper limits of usable spectrum are continuing to be pushed in the 100–200 GHz range. Ofcom, the regulator in the United Kingdom, notes that beyond additional capacity and high-density networks, these bands may offer new opportunities for sensing and high precisions applications.
