Question
Chapter 8, Problem 9ST
Interpretation Introduction
Interpretation:
The molecular formula of fructose is to be stated.
Concept Introduction:
The empirical formula is the simplest whole number ratio of the atoms of the element present in the compound. The empirical formula is determined by the two methods.
• Experimental synthesis data
• Percent composition
Percent composition is mostly used to determine empirical formula. In this method, after calculating the moles of each element in a compound, the mole ratio is simplified to small whole number.
The molecular formula is the formula in which the actual number of each element is shown by the subscript.
