The mole is a quantity in International System of Units (SI) that describes the amount of a substance. Molarity Formula The molarity formula is defined as the moles (mol) of a solute in a liter (L) of solution, the molarity formula requires moles of solute and liters of solution The ...
in other words, the molar mass is the total mass of all the atoms in grams that make a mole of a particular molecule. therefore, the units of molar mass are grams/mole. how to find the molar mass of a compound? step 1. make use of the chemical formula to determine the number ...

Finally, substitute the values of Q, T1, and T2in the heat capacity formula. Grab a calculator or use your brain to perform the calculations and obtain the sample’s heat capacity. The units of heat capacity are J/K. Step 2: Finding Specific Heat Capacity Or Specific Heat ...
To solve for pressure (P) given volume (V), mole (n), temperature (T), and the universal gas constant (R), you can rearrange the Ideal Gas Law equation as follows:P = nRT / VThis equation tells us that pressure is directly proportional to the quantity of moles and the temperature ...
it is measured in debye units denoted by ‘d’. 1 d = 3.33564 × 10 -30 c.m, where c is coulomb and m denotes a metre. the bond dipole moment that arises in a chemical bond between two atoms of different electronegativities can be expressed as follows: μ = 𝛿.d where: μ ...
Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
units of measurement. it’s worth noting that this equation only offers the beginning and final conditions, not the change’s magnitude. subtraction is used to calculate the amount of change. removing the solvent from a solution is part of the concentration process. typically, this is ...
Which one you use depends on whether you have an activation energy in terms of energy per mole (as in chemistry) or energy per molecule (more common in physics). The equations are essentially the same, but the units are different. The Arrhenius equation as it's used in chemistry is ...
