Question

Calculate number of moles in 126 gms of H2SO4.

Answer 1

Answer:

I have solved the question

Explanation:

The most easy step to calculate the moles is

calculate the molar mass

now say molar mass of the compound =1mole

Answer 2

Answer:

Moles = 1.28

Explanation:

Given;-

          Weight, w = 126 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 = 126/ 98

       Moles = 1.28

Hope it helps! ;-))
