Answer:- 0.00724 moles.
Solution:- Grams of salicylic acid are given and it asks to calculate the moles.
For the moles, we divide the grams by the molar mass.
Formula of salicylic acid is
Molar mass = 7(12.01)+6(1.01)+3(16.00)
= 84.07+6.06+48.00
= 138.13 gram per mol
We could make the dimensional analysis set up for showing unit cancellation and have the moles.
= 0.00724 moles
So, there will be 0.00724 moles of salicylic acid in it's 1.00 gram.
Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue reacts with water to produce pink colored
complex.
In this complex, ion forms an octahedral complex with six
ligands.
As is a weak field ligand therefore
ion remains in low spin state.
Hence electronic configuration of ion in this octahedral geometry is
with total three unpaired electrons.
