Answer 1

2) As one mole of aluminium atom contains mole mass = 27 g
so here 1 mole of aluminium atom is used.
then one mole of O2 should also be used.
And molecular weight of one mole of O2 is
= 16g×2= 32g
so, answer (c) is correct.


3) As we know that one mole of any substance contains the number of particles equal to evagadro no.

so here we should see the sulphur here one mole of sulphur is also used in making one mole of Sulphur dioxide.

So the number of atoms are contained in 1 mole of sulphur is also equal to the Avogadro's number.
i.e. 6.022× 10^23 atoms are contained.in sulphur.
so,option (c) is correct.
