Answer:
True
Explanation:
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
About 1.051 moles (depends on how u round it)

Alfred Wegener
Explanation:
Alfred Wegener in 1912, proposed the theory of continental drift from his careful studies of different land masses. From his observations, he suggested the following:
- Some fossils of tropical plants were found in polar and temperate regions.
- Fossils of mesosaurus were found in South America and South Africa now separated by the Atlantic ocean.
- He fitted the continents into a giant land mass puzzles.
- Coal beds in Europe were similar to those in United States.
- Mountain chains in the edge of West Africa was similar to that of Eastern part of South America.
His theory lacked a mechanism which facilitated the plate movement.
