L/4. The weight of a molecule of the compound Co,20e is(A) 1.09 x 102g (B) 2.988 x 10-22 g (C) 5.025 x 10-2g(D) 16.023x 10-2g

Answer»

Molecular weight of C6H12O6 is 180u

But we have to find it in grams.

Since 1u=1.66*10^-24

Therefore 180 u= 1.66*10^-24 *180 =3* 10 ^-22 gram

The answer is Option B.
