Question
Chapter 20, Problem 43QAP
Interpretation Introduction
Interpretation:
The composition of Mn in the sample should be calculated in percent by mass.
Concept introduction:
The moles of any compound or element can be calculated by given formula:
Where n is number of moles, m is given mass and M is molar mass of the element/compound.
The molarity of any compound is the amount of solute dissolved in per liter of solution.
Hence,
Or,
The mass % composition formula is used as:
