A gas occupies 300 ml at `27^(@)C` and 740 mm Hg pressure. Calculate its volume at S.T.P. ? 

Options

A. 0.3650 L
B. 0.2658 L
C. 200 L
D. 365 L

Explanation

Given
`P_(1) = 740` mm , `T_(1) = 300 K , V_(1) = 300` ml
At STP , `P_(2) = 760` mm `T_(2) = 273K , V_(2) = ?`
Now use , `(P_(1) V_(1))/(T_(1)) = (P_(2) V_(2))/(T_(2))`
On solving we get `V_(2) = 265.8 ml = 0.2658 L`
