B Correct answer
Explanation

Given is P = 750 mm =750/760 atm
V = ?,  W = 7.0 gramT = 27o C = 27+ 273 = 300o KR = 0.082, Molecular wt. M = 28. According to ideal gas equation PV = w/M x R x T                                         V = (w x R x T)/(M x P) Substituting the values in this eq.                                              V = (5 x 760 x 0.082 x 300)/(28 x 750)                                                  = 4.451 litres.
