Answer
V1 = 20 lits.
1 lit. = 1000 cc Therefore, 20 lit = 20,000 cc
P1 (Initial pressure) = 100 atmos.
P2 (Final pressure) = 1 atmos.
V2 = ?
By Boyle's Law:
Substituting the values :
200 cc = capacity of 1 flask
Therefore, number of flasks required for 20,00,000 cc of gas
Therefore, number of flask that can be filled = 10,000
