So a for the hydrogen and for helium the velocities hired in the air in the four wagon This is much, much less. The results is the l A city on the Sunday air is because two, three, forty years me too per second. Two moles of helium times four grams of helium per mole of. We can use the molar mass as a conversion factor. So one mole of helium has a mass of 4.0 grams. If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole.
And we know that a t the same tea you want to sound. The molar mass is the mass of one mole of an element and is found on the periodic table. Now Depart sees that Compare your answer for parts A and B and C with the spirit of it with the same temperature. I have Find out this is because too Teo two Teo. Zero two him to underst three make two in four Agon. We replaced with the, um, with this factor. And for the helium, we have again the same form in the gamma too over and out for the helium. Just we put the camera here Is this welcome and em here and teach you injected and you'LL sign it. And to interest Mito close, it can use the calculator to find out the city. I have used a calculated finally developed on the inner city. So re using the numbers here Gamma are too. The spirit of the sound waves were just long to bits. So the temperature we know that this is gonna be the end point one five so we can find out the velocity of the sun. Jules So these are your children for more cash? This never. You know, we had our which is, you know, mostly there's constant art is constant here, and our value is simply eight point three one four. But hire the element number hired more masses. We have more than mass because too thirty nine point nine. Except these are defectors and we know that we know the gamma were given that em the more than mass of different gases more than once with hydrogen gasses to point Jiro too, into dentist forever minus three kanji, but more for helium we have m equals two four point zero zero into tenders toe minus three kg. And for gamma for Agon is it wants to one point. This is Diane Coming? Yes, and for helium, we have got my equals two one point six seven. Remember, the hydrogen dance means that this is a catch too. So we first do the for the hydrogen Gamma is equals to one point for one. This is gonna affect the demise for different for different gases. So this is informed that the velocity this is own formula velocity off the sound wave off the wave in different gases. Lives are different and we have given that the temperature is twenty seven degrees Celsius and reaching kelemen is two hundred point one five. For them, gas is the spirit of the long term. Ask about the speed of the longitudinal face in hydrogen and Aga and then kill him for both for all three Adams.
