Answer:
.371 mole of NaCl
Explanation:
Na Cl Mole weight = 22.989 + 35.45 = 58.439 g/mole
21.7 g / 58.439 g/mole = .371 mole
Answer:
Explanation:
Ph is the major of acidity or basicity of a solution. On a scale of 0 to 14
PH = -log 10 ^(H+)
Therefore PH= -log 10^(6.5) =0.81
Therefore PH of the solution is 0.81
This solution is therefore an acidic solution
Answer:
17.04 g/mol
Explanation:
Molar Mass of NH₃
we know that
Nitrogen has 14.01 gram/mol
And Hydrogen has 1.01 gram/mol
but we have 3 Hydrogens So we multiply
1.01 by 3 i.e., 3.03
Now, add
14.01
+<u> </u><u>3</u><u>.</u><u>0</u><u>3</u>
17.04
So, The molar mass of ammonia, NH₃ is
17.04 g/mol

Answer:
there are no valence electrons left over, so the molecule has four bond pairs and no lone pairs.
Explanation:
I will take a stab at it, but there are not equations, did you forget them?
