Answer : The chemical symbol for this element is, (La)
Explanation : Given,
Mass of = 0.760 g
Mass of = 1.610 g
The given chemical reaction is:
First we have to calculate the moles of and
.
Molar mass of Cl = 35.5 g/mole
Let the molar mass of element 'X' be, M
and,
Molar mass of I = 126.9 g/mole
Let the molar mass of element 'X' be, M
From the balanced chemical reaction we conclude that,
The moles of ratio of and
is, 1 : 1
That means,
From this we conclude that the element (X) is lanthanum (La) that has molecular weight, 138.667 g/mol.
Hence, the chemical symbol for this element is, (La)
