Answer 1

Explanation:

Complete Solution :

And according to the question, 7 % of this molecular weight is sodium. - As we know the molecular weight of a substance constitutes one mole of that substance. And according to this M mass is one mole of methyl orange compound. ⇒M=329g/mol.

Answer 2

Answer:

329

Let M be the minimum molecular weight of the compound.

7% of the compound is sodium. It is equal to

100

7

×M=0.07M g sodium in 1 mole of compound.

At least, 1 mole of Na will be present in 1 mole of compound.

1 mole of sodium weighs 23 g.

Thus, 0.07M=23

M=

0.07

23

=329 g/mol

Thus, the minimum molecular weight of the compound is 329 g/mol.
