Answer: 2.4 ml
Solution :
Molar mass of
= 17 g/mole
Given,: 28% w/w of
solution means 28 g of ammonia in 100 g of solution.
Mass of solution = 100 g
Now we have to calculate the volume of solution.
Molarity : It is defined as the number of moles of solute present in one liter of solution.
![Molarity=\frac{n\times 1000}{V_s}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bn%5Ctimes%201000%7D%7BV_s%7D)
where,
n = moles of solute ![NH_3=\frac{\text {given mass}}{\text {molar mass}}=\frac{28}{17}=1.65moles](https://tex.z-dn.net/?f=NH_3%3D%5Cfrac%7B%5Ctext%20%7Bgiven%20mass%7D%7D%7B%5Ctext%20%7Bmolar%20mass%7D%7D%3D%5Cfrac%7B28%7D%7B17%7D%3D1.65moles)
= volume of solution in liter = 0.11 L
Now put all the given values in the formula of molarity, we get
![Molarity=\frac{1.65moles}{0.11L}=15mole/L](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7B1.65moles%7D%7B0.11L%7D%3D15mole%2FL)
Using molarity equation:
![M_1V_1=M_2V_2](https://tex.z-dn.net/?f=M_1V_1%3DM_2V_2)
![15\times V_1=0.036\times 1.0\times 10^{3}](https://tex.z-dn.net/?f=15%5Ctimes%20V_1%3D0.036%5Ctimes%201.0%5Ctimes%2010%5E%7B3%7D)
![V_1=2.4ml](https://tex.z-dn.net/?f=V_1%3D2.4ml)
Answer:
HOFO = (0, 0, +1, -1)
Explanation:
The formal charge (FC) can be calculated using the following equation:
![FC = V - N - \frac{1}{2}B](https://tex.z-dn.net/?f=%20FC%20%3D%20V%20-%20N%20-%20%5Cfrac%7B1%7D%7B2%7DB%20)
<u>Where:</u>
V: are the valence electrons
N: are the nonbonding electrons
B: are the bonding electrons
The arrange of the atoms in the oxyacid is:
H - O₁ - F - O₂
Hence, the formal charge (FC) on each of the atoms is:
H: FC = 1 - 0 - 1/2*(2) = 0
O₁: FC = 6 - 4 - 1/2*(4) = 0
F: FC = 7 - 4 - 1/2*(4) = +1
O₂: FC = 6 - 6 - 1/2*(2) = -1
We can see that the negative charge is in the oxygen instead of the most electronegative element, which is the F. This oxyacid is atypical.
