Answer:

number of moles of He added = 153.2 moles

Explanation:

given data

initial volume = 2,280 L

final volume = 5,710 L

final volume of helium = 255 mol

solution

we get here initial number of moles of He that is

initial number of moles = \frac{2280}{22.4}  

initial number of moles = 101.8 moles

and

final number of moles is = \frac{5710}{224}  

final number of moles = 255 moles

so that number of moles of He added is

number of moles of He added = 255 - 101.8

number of moles of He added = 153.2 moles

__________ is the inability to distinguish between your own perspective and another person's perspective.
zhenek [66]
The answer would be egocentrism. This is simply the failure to separate one's perspective and other. All the more particularly, it is the failure to unwind subjective patterns from target reality; a powerlessness to comprehend or accept any point of view other than their own. Despite the fact that egocentrism and narcissism seem comparable, they are not the same. A man who is egocentric trusts they are the focal point of consideration, similar to a narcissist, however does not get delight by one's own particular deference.
