Moles â¢ The mass of 1.0 mole of an element is equal to the atomic mass in grams. â¢ One mole element = 6.022 x 10 23 atoms. This number is called Avogadroâs number. â¢ Example: 1 mole of C atoms weighs 12.0 g and has 6.02 x 10 23 atoms.
The Moon travels around the Earth. The Moon travels around the Earth in a circle called an orbit. How long does it take the Moon to orbit the Earth? The Moon takes about 27 days (27 days, 7 hours, 43 minutes, 11.6 seconds) to go all the way around the Earth and return to its starting position. The Moon's orbit around the Earth is a slightly squashed circle called an ellipse.
The Moon takes one circle around the Earth in a little less than 27 days and 8 hours. But since the Moon is circling the Earth while the Earth is circling the Sun, the time iâ¦t takes the Moon to go from full moon to the next full moon (a lunar month, so to speak) is about 29 1/2 days (29 days, 12 hours and 44 minutes). An interesting note: The ancient Mayan's were keen observers of the night sky.
