We can approach this question using the idea of flux lines. First we consider a sphere with a constant density of flux lines at its surface, as is the case for a point mass. These flux lines all point rad...

Re arrange one of the equation to get a single variant answer. So, x = 12 - 3y. Substitute this into the other equation, so 3 (12-3y) + y = 8. Expand this equation to form 36 - 9y + y = 8. Collect the y t...

=(x+4)(x²+6x+5x+30)=(x+4)(x²+11x+30)=x³+11x²+30x+4x²+44x+120=x³+15x²+74x+120

Well this depends whether you require the moles of gas, solid or solution as to which equation you use, moles relate the mass of the atom of interest to that of the number of atoms in 12 grams of carbon-1...
