Molar mass NF₂ => 52.00 g/mol
Atomic mass N => 14 a.m.u
% N = ( Atomic mass N / molar mass NF₂ ) x 100
( 14 / 52 ) x 100 = 26.92%
hope this helps!
Explanation:
Nitrogen triiodide (NI₃)
Valence electrons of nitrogen = 5
Valence electrons of iodine = 7
The total number of the valence electrons = 5 + 3(7) = 26
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
The Lewis structure is shown in image below.
Nitrogen posses one lone pair and thus the geometry is pyramidal.
Answer:
Number of moles
Explanation:
Using the number of moles in chemical reactions, we can determine the quantity of products and even the reactants that are combining to form them.
The number of moles is derived using the expression below is;
Number of moles =
Once we establish the number of moles of any of the specie given from the mass and molar mass, we can relate it to any other species.
It is moldm^-3s^-1
^ means raise to power
Mostly because the lake smell really bad and the waters really dirty
