Answer:B
Explanation:
Atoms and molecules are always moving or vibrating. (just took the test)
Answer: 121.95587 g/mol
Explanation:
- The atomic mass of aluminum is 26.98154 g/mol.
- The atomic mass of phosphorous is 30.97673 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
Therefore, the molecular mass is:
![26.98154 +30.97673 +4(15.9994)=\boxed{121.95587 \text{ g/mol}}](https://tex.z-dn.net/?f=26.98154%20%2B30.97673%20%2B4%2815.9994%29%3D%5Cboxed%7B121.95587%20%5Ctext%7B%20g%2Fmol%7D%7D)
As a noble gas, neon tends to forms no bonds of any kind- so it would be fewest with zero.
Answer : The amount of codeine in one teaspoonful is, 30 mg
Explanation : Given,
Amount of codeine per fluid ounce = 60 mg
Now we have to determine the amount of codeine present in one teaspoonful.
As we know that:
1 teaspoonful = 0.5 fluid ounce
As, the amount of codeine per fluid ounce = 60 mg
So, the amount of codeine 0.5 fluid ounce = ![\frac{0.5}{1}\times 60mg=30mg](https://tex.z-dn.net/?f=%5Cfrac%7B0.5%7D%7B1%7D%5Ctimes%2060mg%3D30mg)
Thus, the amount of codeine in one teaspoonful is, 30 mg
