Calculate the average molar mass of air
WebAnswer (1 of 3): First you get the precentage of airs Like as a example 78% nitrogen , 21% oxygen Now nitrogen get 24 molecular weight and oxygen get 32 weight. Average … WebThe computed theoretical molar mass is somewhat precise when compared to the reference value, which is 48.95, that could be the result of slanting the graduated cylinder too far in the one of attempts, allowing more air to enter, or inaccurately weighing the lighter or leaving some droplets of water in the lighter whilst weighing.
