Question

One gm equivalent of substance present in
1)0.25 mole of O2
2)0.5 mole of O2
3)1.00 mole of O2
4)8.00 mole of O2

Answer 1

Answer:

2

Explanation:

Eq weight of o2 -16/2 =8

and. .5 mole of o2 have 8 gram

which is equal to its Eq. mass

Answer 2

Answer:

(1)

Explanation:

No. of gram equivalence = Given Mass/Equivalent Mass = No. of moles * n - factor

{Equivalent mass = Molar Mass/n - factor}

1) No. of gram equivalence = 0.25 * 4 = 1

2) No. of gram equivalence = 0.5 * 4 = 2

3) No. of gram equivalence = 1 * 4 = 4

4) No. of gram equivalence = 8 * 4 = 32

So, the answer is 1st option, i. e, 0.25 mole of O2
