Question

Twenty molecules of SO3 will weight as much as
molecules of oxygen
100
50
15
8​

Answer 1

Answer:

Correct option is

B

50

The weight of one SO

3

molecule =32+(3×16)

=32+48=80u

Weight of twenty SO

3

molecule =20×80=1600u

Weight of each molecule of oxygen=2×16=32u

Therefore, the no. of oxygen molecules =

32

1600

=50

So, the correct option is B
