Question

An organic compound contains 4% sulphur. It's minimum molecular weight is _______ .
(A)200
(B)400
(C)800
(D)1600​

Answer 1

Answer:

800g

Explanation:

We also know that the weight percentage of sulphur is 4. So, 4 % of the total mass of the organic compound is 32 g. So, the minimum molar mass of organic compound = 100 x 324 = 800 g. So, the correct answer is “Option C”.

Answer 2

Answer:

We also know that the weight percentage of sulphur is 4.

So, 4 % of the total mass of the organic compound is 32 g.

So, the minimum molar mass of organic compound =

$\frac{100×32}{4} \: = 800$

∴ The correct option is (C)800
