Concept explainers
Interpretation:
The molecular formula of a butyric acid has to be given.
Concept Introduction:
Empirical Formula:
The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound. It can be the same as the compound’s molecular formula but not always. An empirical formula can be calculated from information about the mass of each element in a compound or from the percentage composition.
The steps for determining the empirical formula of a compound as follows:
- Obtain the mass of each element present in grams.
- Determine the number of moles of each atom present.
- Divide the number of moles of each element by the smallest number of moles.
- Convert the numbers to whole numbers. The set of whole numbers are the subscripts in the empirical formula.
Molecular formula:
The molecular formula is the expression of the number of atoms of each element in one molecule of a compound if the molar mass value is known the molecular formula is calculated by the empirical formula.

QUESTION Liquid A is known to have a lower viscosity and lower surface tension than Liquid B. Use these facts to predict the result of each experiment in the table below, if you can. experiment Liquid A and Liquid B are each pumped through tubes with an inside diameter of 27.0 mm, and the pressures PA and PB needed to produce a steady flow of 2.4 mL/s are measured. 25.0 mL of Liquid A are poured into a beaker, and 25.0 mL of Liquid B are poured into an identical beaker. Stirrers in each beaker are connected to motors, and the forces FA and FB needed to stir each liquid at a constant rate are measured. predicted outcome OPA will be greater than PB OPA will be less than PB OPA will be equal to PB It's impossible to predict whether PA or PB will be greater without more information.…arrow_forwardShow work.
