Hope this helps :)
Explanation:
In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

Answer:
3.011 x 10^23 molecules
Explanation:
- Mass of Sulphuric (H2SO4) = 49g
-
We have the number of molecules in 49g of H2SO4
Molecular mass of H2SO4 = (Atomic mass of H) x 2 + (Atomic mass of S) x 1 + (Atomic mass of O) x 4
= ( 1 x 2) + (32 x 1) + (16 x 4)
= 2 + 32 + 64
= 98.
Now,
- According to the formula,
Number of moles in the given H2SO4(n) = Mass of H2SO4 in grams/Molecular mass of H2SO4
= 49/98
= 1/2
= 0.5
: n = 0.5 mol
- 1 mol of H2SO4 contains 6.022 x 10^23 molecules.
-
0.5 mol of H2SO4 contains 0.5 x 6.022 x 10^23 molecules.
= 3.011 x 10^23 molecules .
that is 49 g of H2SO4 contains 3.011 x 10^23 molecules of H2SO4.
