Answer:-
Thanks for not describing your question well enough
As we know that one mole of any Ideal gas at standard temperature and pressure occupies exactly 22.4 dm³ volume.
Solution for problem:
When 1 mole Neon (Ne) occupies 22.4 dm³ at STP then the volume occupied by 2.25 moles of Neon is calculated as,
= ( 22.4 dm³ × 2.25 moles ) ÷ 1 mole
= 50.4 dm³ 1dm³ = 1 L
Result:
So, 50.4 dm³ (Liter) volume will be occupied by 2.25 moles of Neon gas if it acts ideally at STP.
Americium has a molar mass of 243 g/mol.
There are 6.022*10^23 atoms in a mol (Avogadro's number).
6 atoms / 6.022 * 10^23 atoms/mol gives us:
9.963*10^-24 mols
Lastly: 9.963*10^-24 mols * 243 g/mol = 2.42*10^-21 g
Answer:
False
Explanation:
using the measurements of the amounts of chemicals, it can be calculated to some degree of accuracy depending mainly on the accuracy of the measurements and enviroments of the reaction
Answer:
the answer is ionic
Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. ... The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows
