Answer:
0.605 molal
Explanation:
molality is the amount of solute in a particular mass of solvent.
lets calculate the amount of benzene solute.
mass of benzene= 13.3g
molar mass of C6H6= 12*6 +1*6 =72+7=78g/mol
amount of benzene= mass/molar mass
=13.3/78
=0.1705mol
molality= amount of solute/mass of solvent in kg
mass of solvent=282g=0.282kg
molality = 0.1705/0.282
=0.605 molal

Pressurized gas is the term that is used to describe a gas that is compressed into a smaller space than it would normally occupy at Earth's surface.
Explanation:
The purpose of compressing a gas is to lessen its volume so that it can fit in a small space. Natural gas can be compressed using a compressor and the pressure of a compressed gas is 200 to 250 bars.
Pressurized gases are used in ground processing and space flight operations. Pressurized gas, also known as compressed gas is also used in fuel production and in gas pipelines.
When stored in a reservoir, care must be taken to avoid leakage as these gases compressed under high pressure are highly flammable.
