A mixture of gases contains H2and O2,gases in the ratio of 1:4 (w/w)

1.	A mixture of gases contains H2and O2,gases in the ratio of 1:4 (w/w). What is the molar ratio ofthe two gases in the mixture? [AIPMT-2015](1) 2:1(2) 1:4(3) 4:1(4) 16:1
Answer» 4:1 Explanation: Number of moles is WEIGHT/mol.mass. Molecular weight of h2 is 2 and that of O2 is 32. So molar RATIO = 1/2 : 4/32 = 4:1
