This is a calculator to convert from concentration, volume, and molecular weight to mass. The calculator can be used to find the mass, volume, or concentration needed to create a solution using a substance with a specific molecular weight.
Mole-Mass and Mole-Volume Relationships The Mole-Mass Relationship To convert the mass of a substance to the number of moles of the substance you have to use the molar mass of an element or compound. Mass = # of moles x (mass/1mole) The Mole-Mass Relationship EX: the molar mass of ...
How much volume does 0.5 moles of oxygen How much volume does 0.5 moles of oxygen take up? take up? Multiply: 0.5 moles x 22.4 Multiply: 0.5 moles x 22.4 ll/mole = /mole = 11.2 11.2 ll How many moles N How many moles N
Volume:体积。 Reactant Moles:反应物摩尔量(写入质量百分含量后,会计算实际摩尔量)。 Reactant Mass:反应物精确质量(写入质量百分含量后,会计算实际质量)。 如底物C5H3F2N是95%含量的,称2.0g底物,实际质量是1.9g。正丁基锂一般都是溶液,如1.6M的丁基锂溶液,输入1.2当量,自动计算出需要的体积是12.38mL。溶剂THF...
Beryllium is a light metal used to fabricate transparent X-ray windows for medical imaging instruments. How many moles of Be are in a thin-foil window weighing 3.24 g? Answer: 0.360 mol Example 4 Deriving Grams from Moles for an Element ...
in which P is pressure in atm (atmospheric units), V is volume in m3(meters cubed), n is the number of moles of the gas, R is the universal gas constant (R = 8.314 J/(mol x K)) and T is temperature of the gas in Kelvin. ...
20 moles H2O x 18g = 360 g H2O TRY IT ON YOUR OWN How many moles of hydrogen peroxide is there in a sample weighing 500 grams Equation: mass/ molar mass 500 g / 32 g H2O2 = 15.62 mole H2O2

Chapter Atomic Processes Sustainable Nuclear Power Example Calculations Example calculations are from DOE Fundamentals Handbook:NuclearPhysicsand Reactor Theory, Volume 1 of 2. Calculation ofMass DefectThe mass defect can be calculated usingEquation 10-1. In calculating the mass defect, it is important ...
as a function of retention volume, where φ is the polymer concentration, η is the solution viscosity, and ηo is the solvent viscosity. Assuming that the retention volume depends uniquely on Vh, regardless of the chemical structure, the distribution in M may be calculated from the relationship...
