![Mol = \frac{mass}{molar mass}](https://tex.z-dn.net/?f=Mol%20%3D%20%20%20%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D%20)
Mass of the compound = 205 g
Molar Mass of compound = ((24) + (2 * 32) + (3 * 16))
= 136 g / mol
∴ # mols in 205g =
![\frac{205 g}{136 g / mol}](https://tex.z-dn.net/?f=%20%5Cfrac%7B205%20g%7D%7B136%20g%20%2F%20mol%7D%20)
= 1.507 mol
You can determine this by looking at the lewis dot structure of the molecule
Answer:
Freeze wedging is caused by the repeated freeze-thaw. Frost wedging occurs as the result of 9% expansion of water when it is converted to ice. Cracks filled with water are forced further apart when it freezes.
Atomic number = 127 – 53=74 neutrons
Answer:
Six
The coordination number of sodium is 6. Likewise, six sodium ions immediately surround each chloride ions, making the coordination number of chloride also equal to 6. Because the formula unit of sodium chloride displays a 1:1 ratio between the ions, the coordination numbers must be the same.
