Question

10g of metal (relative atomic mass 40) are liberated by the passage of 0.5 moles of electrons through molten chloride. What is the formula of chloride? A. M2CL B. MCL C. MCL4 D. MCL2

Answer 1

Answer:

The molecular weight of  will be 200 grams.

Explanation:

We are given a compound having chemical formula  

If, 4 moles of chlorine is present in 1 mole of compound.

Then, 0.5 moles of chlorine will be present in =  of compound.

To calculate the molar mass of compound, we use the equation:

We are given:

Moles of compound = 0.125 mol  

Given mass of compound = 25 g

Putting values in above equation, we get:

Hence, the molecular weight of  will be 200 grams.
