Textbook Problem

A chemist needs exactly 2 moles of KNO3 to make a solution. What mass of solid KNO3 must be used?

Interpretation Introduction

Interpretation:

Molar mass and mass (grams) of the solid are calculated

Concept Introduction:

Molar mass is the mass of one mole of a compound. It is expressed in g/mol. Molar mass of compound is the sum total of mass of all the elements present in it.

To determine:

Mass of 2 moles of solid KNO3

Explanation

Molar mass of KNO3 is the mass of one mole of it.

Molar mass of KNO3 = 1×molar mass of K+ 1×molar mass of N + 3×molar mass of O

Molar mass of KNO3 = 1×39
