someone pls explain that how the hell is   1/12th mass of 1 carbon atom multiplied by 6.023 * 10^23 give 1 as the product

If both roots of ax^2+bx+a-c =0 are imaginary and a b and c are real numbers and c>-1 then establish relation between a b and c

Guys plz check whether this question is wrong or not :-
In H atom the energy of electron in the nth orbit is given as En = -13.6/n².
Show that E(n+1) - En = -13.6/n²  eV*2 for large value of n.

#By large value of n ---> you can consider n+1 ~ n

1 mole mixture of N2,NO2,N2O4 has a mean molar mass 55.4 on heating to temprature at  which all hte N2O4 dissociate  into NO2 according to raction
(N2O4 double headed arrow 2NO2) and average molar mass becomes 39.6.what is the mole ratio of N2,NO2,N2O4 ????? [ANSWER:0.5:0.1:0.4]
