Concept explainers
Interpretation: The M in formula MO2 needs to be identified, if it contains 40.1 % of oxygen by mass.
Concept Introduction: Mass percentage is the way to calculate the percentage of each element in the given molecular compounds. The mathematical expression of mass percentage can be shown as:
Answer to Problem 12STP
The metal with 47.8 g/mol is Titanium.
Explanation of Solution
Given information:
Mass percentage of O = 40.1 %
Mass percentage of O = 40.1 %
Molar mass of O = 16.0 g/mol
1 mole of MO2 = 2 moles of O
Mass percentage of M= 100 − 40.1 = 59.9 %
The metal with 47.8 g/mol is Titanium.
The metal with 47.8 g/mol is Titanium.
