1.	Suppose the chemists had selected 10^20 as the number of particles in a mole. The molar mass of oxygen gas would be (Use Avogadro number = 6.0 xx 10^23)
Answer» `5.33xx10^(-3)g` `5.35xx10^(-23)g` `5.33xx10^(-43)g` `32xx10^(3)g` SOLUTION :`6xx10^(23)` molecules of oxygen weighs 32 g 1 molecule of oxygen weighs `(32)/(6xx10^(23))` `10^(20)` molecules of oxygen weighs `(32xx10^(20))/(6xx10^(23))=5.33xx10^(-3) g`
