Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform a number of different calculations for preparing molar solutions when starting with the solid material. For example, the known molecular weight of a chemical can be used along ...
Be able to calculate the molar concentration given the mass of solute, formula weight, and volume of solution • Be able to calculate the number of moles of solute in an aliquot of solution given the volume and concentration • Be able to determine the gram molecular weight of simple comp...
A mixture composition often is given simply in percent, but the percent is calculated on a mass (or weight) basis,1 a molar basis, a volume basis, or a pressure basis; and the numerical values depend on which basis is used in the calculation. This ambiguity leads us to define four ...
The atomic mass of hydrogen is1.00794and oxygen is15.9994. The formula to calculate the molecular weight based on the atomic weights looks like this: molar mass = 1.00794 (H) + 1.00794 (H) + 15.9994 (O) Therefore, the molar mass of H2O is18.01528 g/mol. ...
The method comprises the following steps: (1) performing a reduction-oxidation reaction between an H2S feed gas and oxygen in an oxygen-rich gas to prepare SO2, controlling residual oxygen after the reduction-oxidation reaction step at amolarpercent of ≥ 2%; (2) cooling the product acquired ...
In this paper, these two rules are expressed by three different concentration units(mole raction, molality and weight percent) and are extended to the general linearconcentration rules at constant partial molar uantity Ψ_0 applicable to all thermo-dynamic properties Ψ of any n-component (n≥3...
However, compared to the known value of 46.1 g of ethanol, the value measured had a 108% error. Unfortunately, this was a very big percent error and may have been caused by incorrectly measuring the volume of the gas. Using the ideal gas law, the molar mass of a volatile compound was...
