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 orbits the Earth at approximately 2,288 miles per hour and completes one full orbit every 27.322 days. Additionally, the moon takes approximately 27 days to complete one full rotation on its own axis, called its rotational period, which closely matches its orbit around Earth. Continue Reading.
