1.       In order to prevent the condition called “bends”. He needs to calculate the Molar Mass of the mixture of 10.0% 02, 10.0 % N2 and 80 % He.So the Answer is letter A. Calculate the molar mass of this mixture.How to calculate:Given Numbers : 10.0 % O2                               10.0% N2                               80 % HeMolar Mass = (.10 x 32g / mol.) + (.10 x 28g / mol.) + (.80 x 4g / mol.)                          => 9.2g / mol
