Answer:
The breakup sort of resembles the Pangea since the Pangea was a large supercontinent before it split into smaller continents. The plates are also moving a slow rate similar to how Pangea slowly broke up.

In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.
The average pea weighs between 0.1 and 0.36 grams.
If we take the lower value (0.1 g/pea), the number of peas in 454 g is:

If we take the higher value (0.36 g/pea), the number of peas in 454 g is:

In a bag of peas that weighs 454 grams, there are between 1261 and 4540 peas.

The concentration of the solution is 4.25 M
Explanation
molarity=moles/volume in liters
moles = mass/molar mass
molar mass of HF = 19 + 1 = 20 g/mol
moles is therefore = 17.0 g/ 20 g/mol = 0.85 moles
volume in liters = 2 x10^2ml/1000 = 0.2 liters
therefore molarity = 0.85/0.2 = 4.25 M
