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.
How long does it take our Moon to go around Earth? It takes 27 days, 7 hours, and 43 minutes for our Moon to complete one full orbit around Earth. This is called the sidereal month, and is measured by our Moon's position relative to distant fixed stars.However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).This is called the synodic month. The difference between the sidereal and synodic months occurs because as our Moon moves around Earth, the Earth also moves around our Sun.his is called the sidereal month, and is measured by our Moon's position relative to distant fixed stars. However, it takes our Moon about 29.5 days to complete one cycle of phases (from new Moon to new Moon).
