Explanation Consider the mass of magnesium boron compound as 100 g . So, 100 g of superconductor contains 52.9 g of Mg. The number of moles of magnesium is calculated as follows: Moles of Mg = 52 .9 g of Mg × 1 mol of Mg 24 g of Mg = 2 .204 mol of Mg Similarly, 100 g of superconductor contains 47.1 g of B. The number of moles of boron is calculated as follows: Moles of B = 47

Question

Chapter 3, Problem 139RQ

Interpretation Introduction

Interpretation:

The formula of superconductor has to be determined.

Concept Introduction:

The conversion factor is a fraction obtained from a relationship between the units. It is written as a ratio and can be inverted to give two conversion factors for every relationship.

The appropriate conversion factor for any equality is selected in such a way, so that it results in the proper unit cancellation.
