Answer:
ii. 
Explanation:
Isoelectric species are the species which have same number of electrons.
From the given options:-
are the isoelectric species.
All the three species have same number of electrons which is equal to 6.
Carbon has 6 electrons.
has 6 electrons.
has 6 electrons.
Just add more detail in the second experiment explain every little thing.
The answer is 37.5 moles
The explanation:
1- when we have the mass of SO3 in Kg so, first we have to convert it to grams:
mass = 3 * 1000 = 3000 g
2- we need to get the molar mass of SO3 :
molar mass of SO3 = 32 + (16*3)
= 80 g/mol
3- then we can use this formula to get number of moles:
moles = mass / molar mass
= 3000 g / 80 g/mol
= 37.5 moles
