Simplest formulas are determined by establishing the mass of each element present in a given mass of the compound. From those masses one finds the number of moles of each element. The mole ratio must be equal to the atom ratio in the compound and from that ratio the simplest (empirical) ...

Molecular Formula of Ammonium Nitrate A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: ...
The percent by mass is a measure of the elemental composition of compounds. In calculating the percent by mass, the molar masses of the component elements are required, and the molar mass is written in terms of grams per mole or g/mol....
To calculate the specific heat capacity (C) of any substance, you will need a specific heat capacity formula (equation, if you will). Further on, you will also find a specific heat capacity calculator: You just plug in Q (heating energy), m (mass), and ΔT (temperature difference), ...
(NH3) is 1.49D. This is because BH3has a symmetrical structure and the 3 B-H bonds are placed at an angle of 120 degrees to each other. As the 3 bonds are in a single plane, dipole moments cancel each other, with net dipole moment equal to zero. On the other hand, NH3has a ...
