Question

Which of the gases in the graph below has the largest molar mass? A B C D There is not enough information to determine. The titration of 25.0 mL of an unknown concentration H_2SO_4 solution requires 83.6 mL of 0.12 M LiOH solution. What is the concentration of the H_2SO_4 solution (in M)? 0.20 M 0.40 M 0.25M 0.10M 0.36M How many milliliters of 0.260 M Na_2S are needed to react completely with 45.00 mL of 0.315 M AgNO_3? 109 mL 27.3 mL 54.5 mL 74.3 mL What pressure (in atm) will 0.44 moles of CI_2 exert in a 2.6 L container at 25 degree C? 4.7 atm 4.1 atm 8.6 atm 0.35 atm 3.6 atm A 0.465 g sample of an unknown compound occupies 245 mL at 298 K and 1.22 atm. What is the molar mass of the unknown compound? 33.9g/mol 26.3 g/mol 81.8 g/mol 12.2g/mol 38.0 g/mol According to the following reaction, what mass of PbCl_2 can form from 235 mL of 0.110 M KO solution? Assume that there is excess Pb(NO_3)_2. 1.80 g 1.30 g 3.59 g 5.94 g 7.19 g

Explanation / Answer

14.

Here the option D is the correct answer

As we know that Graham's Law,

speed of the molecules directly proportional to Temperature and inversely varies with molar mass.

Here in this graph lowest peak is obtained for A, because relative number particles is very low that means we can argued that it contain Highest Temperature and has low mass of molecules whereas in case point A , temperature is very low and carry large number of particles. Hence at point D , the molar mass is very high.
