Answer:
Explanation:
First, find the molar mass of calcium (Ca). This can be found on the Periodic Table.
- 40.08 g/mol
Next, find the number of moles.
Avogadro's Number tells us the number of atoms in one mole.
- It is 6.023*10²³
Therefore, there are 6.023*10²³ atoms in 1 mole.
We have 6.023*10²³ atoms of calcium, so it must also be 1 mole of calcium.
Finally, find the mass. Set up a proportion using the molar mass of calcium.
Multiply. The moles (mol Ca) will cancel.
There are <u>40.08 grams </u>in 6.023*10²³ atoms of calcium.
