Q.39. A 0.5 d m 3 flask contains gas A and 1 d m 3 flask contains gas B at the same temperature. If density of A is twice that of B and the molar mass of A is half of B, then the ratio of pressure exerted by gases is (a) P A / P B = 2 (b) P A / P B = 1 (c) P A / P B = 4 (d) P A / P B = 3 Share with your friends Share 7 Keerthana P answered this Please find this answer 6 View Full Answer Keerthana P answered this Please find this answer 8
