How the helium is 4 g suggest these method
Answers
Answer:
if you are asking that why is helium a molecular mass is 4 then it is explained below
Explanation:
helium helium atom has two proton and two neutron in its nucleus and if you had studied atomic structure then you must have read somewhere that the overall mass of an atom is concentrated in its nucleus as such the gram molecular mass of helium is 4 the four comes up from the sum of number of protons and neutrons present in nucleus of it.
there is another method of explaining the reason behind mass of helium atom to be 4 gram but I don't think so you will understand it as exactly as I had explained above but because it is a fact I would like to tell it to you only that
the four Gram comes from the relative mass comparison with carbon
if you find this answer correct and acceptable then please do not forget to give it start writing and thanks to it also you can you can follow me on brainly and I will make sure that all your doubts in chemistry will be cleared
