Question

Q.12 A sample of 0.600 mol of a metal M reacts completely with excess of fluorine to
form 46.8 g of MF,
b) Which element is represented by the symbol M?

Answer 1

Answer:

Here, we are calculating the each of the following.

Step 1 of 3

a.

Let’s calculate the moles of F in MF2

Given

Moles of M = 0.600 mol

The given molecular formula - MF2

From the molecular formula moles fluorine is twice than the moles of metal M.

Number of moles = 2 x M

= 2 x 0.600

= 1.2 mol.

Therefore, 1.2 mol of Fluorine are in the sample of MF2 that forms
