Question

4 g of divalent metal reacts with chlorine to produce 11.1 g of its metal chloride. Calculate the atomic mass of metal.

Answer 1

Explanation:

To find the number of moles of chlorine here,divide its masses (11.1-4 =7.1gram )

by its molar mass .

Then 4g of 'M' is ½that number of moles.

Divide this into the mass (4g) to get the atomic mass......
