The Federal Communications Commission (FCC) is an independent agency of the United States government, created by Congressional statute (see 47 U.S.C. Â§ 151 and 47 U.S.C. Â§ 154) to regulate interstate communications by radio, television, wire, satellite, and cable in all 50 states, the District of Columbia and U.S. territories.
Water consists of H2O molecules that each conprise 3 atoms. A typical H2O molecule as a molecular weight of 18, disregarding isotopes. That means one mole weighs 18 grams. 1000 g / 18 g = 55.6 mole H2O in a liter of water. One mole is around 6 x 10^23 so around 3 x 55.6 x 6 or 1000 mole atoms. Wolfram|Alpha confirms: how many atoms are in a liter of water.
For the H2CO Lewis structure, calculate the total number of valence electrons for the H2CO molecule. After determining how many valence electrons there are in H2CO, place them around the central atom to complete the octets. B. There are a total of 12 valence electrons in the Lewis structure of H2CO.
