Question

a cylinder of 20 litres capacity contains a gas at hundred atmospheric pressure how many flasks of 200 cubic centimeter capacity can be filled from it at 1 atmospheric pressure,temperature remaining constant​

Answer 1

Answer:

Since all gases have the same volume per mole at a given temperature and pressure far from their points of liquefaction and solidification (see Perfect gas), and air is about 1/5 oxygen (molecular mass 32) and 4/5 nitrogen (molecular mass 28), the density of any near-perfect gas relative to air can be obtained to a good approximation by dividing its molecular mass by 29 (because 4/5 × 28 + 1/5 × 32 = 28.8 ≈ 29). For example, carbon monoxide (molecular mass 28) has almost the same density

Answer 2

Question:

A cylinder of 20 litres capacity contains a gas at 100 atmospheric pressure. How many flasks of 200 cm³ capacity can be filled from it at 1 atmosphere pressure, temperature remaining constant?

Answer:

Given:

V1=20L=20000cm³

P1=100atm

V2=?

P2=1

According to Boyles' Law,

P1V1=P2V2

Solution:

100 × 20000 = 1 × V2

2000000 = V2

Also asked that,

how many flasks of 200 cm³ capacity can be filled from it at 1 atmospheric pressure and temperature remain constant.

Therefore,

According to Question:

2000000cm³ ÷ 200cm³

=10000 flasks Ans
