Answer 1

here is your answer.hope it will help you.

Answer 2

Answer:

Hence, option (d) 60g is correct.

Explanation:

Concept:

What is molecular weight?

The average mass of a compound's molecules, measured as the sum of the atomic weights of its constituent atoms and equivalent to 1/12 the mass of carbon 12.

Calculation:

Let the minimum molecular weight of the compound be x $\frac{g}{mol}$.

There will be at least one carbon atom present.

1 mole of a chemical weighs x g, or 12 g, or at least 1 carbon atom.

We are aware that a chemical must include just one oxygen atom in order to have a minimum molecular weight.

So, X x $\frac{20}{100} = 12$

     X x $\frac{1}{5} = 12$

      x = (12 x 5)g

      x = 60g

As a result, the compound's minimum molecular weight is 60 g.
