Question

The element A and B have atomic weights 12.0 and 35.5 respectively. A and B combine to form a new substance X. If four moles of B combine with one mole of A to give one mole of X, then the weight of one mole of X is....?​

Answer 1

Answer:

Molar mass = 154 g mol⁻¹

Explanation:

As given,

A and B combine to form new substance X.

Here,

4 moles of B combine with 1 mole of A to give 1 mole of X.

A + 4B ⇒ X

Hence,

Molar mass of X = 12.01 + (4×35.5)

∴ Molar mass = 154 g mol⁻¹

Answer 2

Answer:

Explanation:

So A will be carbon and B will be Chlorine and the product formed is CCl4(Carbon tetrachloride)

1 mole of CCl4= 12+4*35.5=154grams
