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.
It takes about four weeks for the Moon to orbit once around Earth. During this time, the Moon's position relative to Earth and the Sun is constantly changing. During part of its journey, the Moon is between Earth and the Sun.Then, a few days later, it is off to one side.he Moon itself puts out no light at all.
