25cm3 of a mixture of nobel gases was obtained from air after the removal of other constituents. What was the original volume of air
A
2,500 cm3
B
1250 cm3
C
125 cm3
D
80 cm3
correct option: a
Percentage of noble gases in air is 1%
25 = (1/100) * T
∴ T = 25 * 100 = 2500 cm3
25 = (1/100) * T
∴ T = 25 * 100 = 2500 cm3
