Answer:

2–methyl–2–propanol.

Explanation:

To name the compound given in the question above, we must:

1. Identify the functional group and it's location on the compound.

2. Locate the longest continuous carbon chain. This gives the parent name of the compound.

3. Identify the substituent group attached to the compound.

4. Locate the position of the substituent group.

5. Combine the above to obtain the name of the compound.

Thus, we can obtain the name of the compound as follow:

1. The functional group of the compound is alkanol (alcohol). It is located at carbon 2.

2. The longest continuous carbon chain is 3. Since the compound is an alcohol, parent name of the compound will change from propane to propanol.

3. The substituent group attached to the compound is methyl i.e –CH3.

4. The methyl group is located at carbon 2.

5. The name of the compound is

2–methyl–2–propanol.

how much sodium chloride must be added to 100 mL of water so that its concentration is 20 parts per million assume that the dens

OlgaM077 [116]

Answer: 2mg

Part per million is unit that equal to mg/kg of water or simply $10^{-6}$ . In this case, you asked how much NaCl needed and know the volume of water(100mL), concentration(20ppm or 20 mg/kg) and water density.
Then, the equation would be

concentration = NaCl weight/ water weight
20 x $10^{-6}$ mg= NaCl weight/ (100ml x 1g/ml)
NaCl weight= 20x $10^{-6}$ mg/kg x 100g
NaCl weight= 2000 x $10^{-6}$ g
NaCl weight= 2x $10^{-3}$ g = 2mg
