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.
How many kJ of heat are needed to completely vaporize 43.2 g of H2O? The heat of vaporization for water at the boiling point is 40.6 kJ/mole. How many kJ of heat are needed to completely melt 3.30 moles of H2O, given that the water is at its melting point? The heat of fusion for water is 6.02 kJ/mole. How many kJ of heat are needed to completely vaporize 1.30 moles of H2O? The heat of vaporization for water at the boiling point is 40.6 kJ/mole. How many joules of heat are needed to completely vaporize 43.2 grams of water at its boiling point?
