If you mean lewis dot symbol you need a nuclide you get the number of proton (z) its equal to electrons since the atom is nutral then you make the elctron configuraion after that you take the number of electrons on the outer energy level( ex:k²L² in this case its the 2 on the L)and if you have 7 electrons and the atom is nitrogen so it becomes

Hope that helped
The answer is 0.25 moles because one mole of NH3 would have apporximately 6.02X10^23 molecules
One mole in n2 is equal or 28.0134 grams
Isomers are compound having same molecular formula but different structure formula
The molecular formula of butanoic acid and ethyl acetate is C4H8O2.
The structure formula of butanoic acid is CH3CH2CH2COOH, while structural formula of ethyl acetate is CH3COOCH2CH3.
Thus, both butanoic acid and ethyl acetate have same number of constituent atoms, therefore they have same atomic mass. Thus, molecular mass of ethyl acetate is 88.1 amu.
I would say the answer is <span>dust and rocks
The regolith is a layer of material that covers solid rock. it is made of dust and soil.</span>
