Molarity is also known as molar concentration. This is the ratio between numbers of moles of a substance in one volume of a solvent. Conventionally, the solvent volume is given in cubic meters. However, for our convenience, we often use liters or cubic decimeters. Therefore, the unit of t...
Formula mass and molar mass are two physical properties of molecules that show some difference between them. Both of these parameters, the formula mass and molar mass, are related to the weight of chemical elements (atoms, molecules, unit cells). Sinceatoms, molecules, and unit cells are extre...
Compute the difference in masses of one mole each of aluminium atoms and one mole of its ions? (Mass of electron is 9.1×10−28 g). Which of one is heavier? View Solution The difference in the mass of 100 moles of each of sodium atoms and sodium ions is 5.48002 g. Compute the ma...
What is the difference between solubility and miscibility?Question:What is the difference between solubility and miscibility?Solubility:The solubility of a substance is its ability to dissolve in a given solvent, like how table salt dissolves in water while other substances can not. Some substances ...
What is the difference between 0.05 g and 5.0 xx 10^(-3)g ? 01:28 Are the molar volumes of CO(2) and SO(2) different ? 01:38 It the atomic masses of C and S are 12 and 32 respectively, then atom ... 01:11 How many oxygen are present in 96 g of ozone ? 03:06 Which ...
Is the molar enthalpy of formation a type of enthalpy change? Or, is it just how much energy is absorbed as heat when one mole of a compound is formed? What is the difference between physical and chemical properties in science? Can you explain chemical energy? ...
The definition of molecular weight is directly related to thecarbon-12isotope. The mass of one mole of carbon 12 atoms is exactly 12 grams, so its molar mass is exactly 12 grams per mole. Moreover, we can calculate the molecular weight of molecules containing the same atoms like O2 or N2...
The infrared analysis of the temperature dependence of the intensities of the ν(C O) absorption bands of cyclohexanol shows that the enthalpy difference between the equatorial and axial conformers is Δ H = 376 ± 51 cal/mole. It is shown also that for this derivative ΔH ΔF, and, ...
Avogadro's Constant refers to the number of particles in one mole of substance (6.02214076×10²³ mol⁻¹), expressed with units, while Avogadro's Number is the dimensionless value of this constant, approximately 6.022×10²³.
This brings up a common mistake people make when preparing molar solutions. It's important to dilute a molar solution to the correct volume rather than add a volume of solvent. For example, if you're making 1 liter of a 1 M NaCl solution, you would first measure one mole of salt, add...
