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.
1 Answer. The Moon, located an average distance of 380,000 km away, orbits the Earth at an average speed of about 3,680 km/hr and completes its orbit in about 27.25 days. The orbit is tilted about five degrees to the ecliptic plane. The 27.25 days is the length of the sidereal month, just over 2 days shorter than the lunar month of 29.5 days.
