Answer= 0.144gWorking out:mol= conc x volume (in dm^3)mass = mol x RFFSo,mol = 0.18 x (20/1000) = 0.0036molMass= 0.036 x 40 = 0.144g

Okay so first always write out the equation...N₂(g) + 3H₂(g) ⇌ 2NH₃(g)Now we need to ask ourselves what equations we know are relevant to the question. The question gives ...

20/1000 *0.18
final answer 0.144 Answer must be explained in person. It is very difficult to explain in writing.

To answer this question, we need to know the relative number of atoms of each element present. This can be calculated by dividing the amount of an element present in the sample by the relative masses of t...

The elements in the periodic table are arranged in terms of atomic number. i.e. hydrogen is first as it has 1 proton, then helium with 2, lithium with 3 etc.Elements in the same group have the same number...
