Answer:
0.0073 g
Explanation:
Considering:
Or,
Given :
For HCl :
Molarity = 0.010 M
Volume = 25 mL
The conversion of mL to L is shown below:
1 mL = 10⁻³ L
Thus, volume = 25×10⁻³ L
Thus, moles of HCl :
Moles of HCl = 0.00025 moles
Considering the reaction shown below as:-
2 moles of HCl reacts with 1 mole of
So,
1 moles of HCl reacts with 1/2 mole of
Also,
0.00025 moles of HCl reacts with mole of
Mole of = 0.000125 moles
Molar mass of = 58.3197 g/mol
Mass = Moles*Molar mass = = 0.0073 g
NH3 is a molecule with a nitrogen atom in the middle surrounded by 3 hydrogen atoms bonded covalently. Nitrogen has 5 valence electrons so, it will form sigma bonds (sp3 hybrid orbitals) with each of the hydrogen atom. The remaining lone pair electrons will be situated above the atom. You ca look at this image I've pulled from Google.
