Mass in grams of 6.023×1023 atom of Ca
1 answer:
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.

The Lewis formula refers to a diagram showing the distribution of electrones and in case of a molecule it also shows the bonds.
The structural formula on the other hand is a representation of the molecular structure that shows all the atoms that form the molecule, arranged in a three dimentional space,
In this case we have the hydrogen ion, which is the simpliest case we can have.
Hydrogen ion is the hydrogen atom possitively charged as it has lost his electron. Therefore the structural formula is simply the following:
The Lewis formula is also very simple as this ion has no electrons and has no bonding to other atoms:
