6.023*1023 He atoms=1 mole He
1.23×1024 helium atoms=1.23×1024/6.023*1023 =2.042 mole He
one mole He=4.0 gm
2.042 mole He=2.042*4.0=8.168 gm
answer in grams of Helium is 8.168 gm
The element that is used as a rat poison and found of the murder mystery is Arsenic.

Answer:
Explanation:
Here, we want to get the new volume of the gas
What we need to know is the law that connects volume and pressure at constant temperature
The law that supports this is the Boyle's law
It states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature
Mathematically, we can have this as represented as:

We can proceed mathematically to solve as follows;
1.
Take Lithium for an example. It would be able to fill up the 1s orbital, but then once it tried to fill up the 2s orbital, it would only have one electron left, since each s orbital can hold 2 electrons.
