Explanation:
As it is known that molarity is the number of moles present in a liter of solution.
Mathematically, Molarity = ![\frac{no. of moles}{Volume in liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bno.%20of%20moles%7D%7BVolume%20in%20liter%7D)
As it is given that molarity is 0.10 M and volume is 10.0 ml. As 1 ml equals 0.001 L. Therefore, 10.0 ml will also be equal to 0.01 L.
Hence, putting these values into the above formula as follows.
Molarity = ![\frac{no. of moles}{Volume in liter}](https://tex.z-dn.net/?f=%5Cfrac%7Bno.%20of%20moles%7D%7BVolume%20in%20liter%7D)
0.10 M = ![\frac{no. of moles}{0.01 L}](https://tex.z-dn.net/?f=%5Cfrac%7Bno.%20of%20moles%7D%7B0.01%20L%7D)
no. of moles = 0.001 mol
As molar mass of KCN is equal to 65.12 g/mol. Therefore, calculate the mass of KCN as follows.
No. of moles = ![\frac{mass}{molar mass}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D)
0.001 mol = ![\frac{mass}{65.12 g/mol}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7B65.12%20g%2Fmol%7D)
mass = 0.06152 g
Thus, we can conclude that 0.06152 grams of KCN are in 10.0 ml of a 0.10 M solution.
Answer:
Think of each polar bond in a molecule as a little arrow pointing from positive to negative. This tells us that the bond dipole is a vector quantity. Like any other vector quantity, the direction is a vital aspect of its description. So, the geometry of the molecule determines the direction that the bond dipole vectors point. The polarity of the molecule results from adding up all these individual bond dipoles.
