Answer 2

Answer:

Moles = 2

Explanation:

Given;-

          Weight, w = 196 g

Molecular Weight, MW = H₂SO₄

                                       = 1×2 + 32 + 16×4

                                       = 98 u

Now, we know by formula that;-

       Moles = Weight / Molecular Weight

Putting the given values in the question we get;-

       Moles = 196/ 98

       Moles = 2

Extra Information:

A moles is comprised of Na ( Avogadro number ) of entities. The entities can include atoms, molecules, ions, etc.

1 Avogadro , Na = 6.022 × 10²³
