Question

volume of 1.5gram atoms of helium at s.t.p

Answer 1

1.5/4= moles of helium
m= 0.375..but me knows that
$1mole = 22.4l$
so o.375 moles
$22.4 \times 0.375 = 8.4l$
so the volume of 1.5g helium in stp is 8.4L
thanks

I hope it will help u
and plzz mark me as brilliant

Answer 2

Answer:

Explanation:

1.5 gram atom is nothing but 1.5 mole , so as we know that 1 mole of Helium occupies 22.4 lit at S.T.P , we want volume of 1.5 mole of Helium so therefore 22.4 × 1.5 and that is equal to 33.6 lit
