4.42 g mass of CCl4 is required to prepare a 0.25 m solution using 115 g of hexane.
It's easy to find the molecular mass of a compound with these steps: Determine the molecular formula of the molecule. Use the periodic table to determine the atomic mass of each element in the molecule. Multiply each element's atomic mass by the number of atoms of that element in the molecule.
The molar mass of any compound can be found out by adding the relative atomic masses of each element present in that particular compound.
Hexane is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C₆H₁₄.
Therefore,
⇒ 0.115 g of Hexane x (0.25 mol CCl4/1 mol hexane) x (153.81 g of CCl4/1 mol CCl4) = 4.42g CCl4.

Answer:
Exit velocity of air is 96.43 m/s.
Explanation:
Given that



For air

Now from first law of thermodynamics for open system at steady state
For diffuser
We know that


So the exit velocity of air is 96.43 m/s.
The location that volcanoes are consistently found in the world is near the Ring of Fire so the answer would basically be "Continent-ocean boundaries".
