Concept explainers
Interpretation:
The empirical formula and the molecular formula of peroxyacylnitrate (PAN)are to be calculated with given percent by mass of element present and molar mass.
Concept introduction:
Empirical formula is the simplest formula of any compound when written in the least possible whole number without altering the relative number of atoms.
The molecular mass of any compound is the sum of the
The percent composition of an element by its mass in a compound can be calculated as
Here, n represents the number of atoms in the given molecule or compound.
The number of moles is defined as the ratio of mass to the molar mass:
Here,
The mass of compound can be calculated as
Here,
The molecular formula can be calculated as

- 3.96 Methyl cyanoacrylate is the chemical name for the substance sold as Super Glue, and it has the chemical formula C5H5NO2. Calculate the number of molecules of this substance in a 1.0-ounce tube of Super Glue, assuming that the glue is 80% methyl cyanoacrylate by mass.arrow_forwardUranium is used as a fuel, primarily in the form of uranium(IV) oxide, in nuclear power plants. This question considers some uranium chemistry. A small sample of uranium metal (0.169 g) is heated to 900 °C in air to give 0.199 g of a dark green oxide, UxOy. How many moles of uranium metal were used? What is the empirical formula of the oxide UxOy? What is the name of the oxide? How many moles of UxOy, must have been obtained? The oxide UxOy is obtained if UO2NO3 · n H2O is heated to temperatures greater than 800 °C in air. However, if you heat it gently, only the water of hydration is lost. If you have 0.865 g UO2NO3 · n H2O and obtain 0.679 g UO2NO3 on heating, how many molecules of water of hydration were there in each formula unit of the original compound?arrow_forwardVitamin A has a molar mass of 286.4 g/mol and a general molecular formula of CxHyE, where E is an unknown element.
