Chapter 2, Problem 86IAE

Interpretation Introduction

Interpretation:

The mass percent composition of eutectic alloy (Sn-Pb-Cd) needs to be determined, if the mole ratio of Sn: Pb is 2.73:1.00 and mass ratio of Pb: Cd is 1.78:1.00.

Concept introduction:

The number of atoms is directly proportional to number of moles of the atom. The number of moles is related to mass and molar mass of a substance as follows:

$n=\frac{m}{M}$

Here, m is mass and M is molar mass.

The atomic mass is mass of 1 mol of an atom.
