Hello!</h2>
The answer is:
There are 732.24 grams of Dinitrogen Pentoxide 
in 6.78 moles of the same compound.
<h2>
Why?</h2>
The dinitrogen pentoxide, or nitrogen pentoxide, is a rare salt that consists of anion and cations, and it's an important compound when preparing some kinds of explosives.
So, to answer the question, first, need to look for the molecular formula of the dinitrogen pentoxide, then, use it to calculate the mass in gram of 6.78 moles of the same compound.
The dinitrogen pentoxide formula is:
Where, the molar mass of each element are:
Calculating the molar mass of the compound, we have:
Now, calculating what is the mass of 6.78 of , we have:
So, there are 732.24 grams of Dinitrogen Pentoxide in 6.78 moles of the same compound.
Have a nice day!
NaHCO₃ (s) + HCl (aq) → NaCl (aq) + CO₂ (g) + H₂O (l)
From reaction coefficient: mole NaCl = mole NaHCO₃ = 0.0119
so mass NaCl:
= mol x Mr NaCl
= 0.0119 x 58.5 g/mol
= 0.696 g
The answer is that; the outermost shell of all atoms with two or more electron shells will not have more than 8 electrons.
Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the outermost energy level. On the other hand elements in the same period have the same number of energy levels and differ in chemical properties since they belong to different groups.
