Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
Determination of the Dissociation Constant and Molar Mass for a Weak AcidAbstract: We will determine Ka and the molar mass for an unknown weak acid by using a pH meter to record the pH at intervals during the titration with sodium hydroxide. The titration curve and its first derivative will be plotted to establish the equivalence point. Introduction The strength of an acid is defined by its ability to donate a proton to a base. For many common acids, we can quantify acid strength by expressing it as the equilibrium constant for the reaction in which the acid donates a proton to the standard base, water, as shown in the equations below: HA + H2O Û H3O+ + A-, for H3CCOOH: H3CCOOH + H2O Û H3O+ + H3CCOO - The equilibrium constant for a reaction of this type is called the Acid Dissociation Constant, "Ka", for the acid HA Determination of the Dissociation Constant and Molar Mass for a Weak AcidAbstract: We will determine Ka and the molar mass for an unknown weak acid by using a pH meter to record the pH at intervals during the titration with sodium hydroxide.

Btu / scf = Btu / lb X MW / 379.5 where: MW = molecular weight of the gas, lb / lb-mol The constant 379.5 is the molar volume at standard conditions of 14.696 psia and 60°F
In chemical engineering, we deal with molar fluxes and I am very sure molar flux is not a vector, it is simply a scalar. molar flux cannot be negative because you cannot have - 5.0 moles of something flowing but I think you'll have to verify for other cases like magnetic flux and electrical fluxes
Molar extinction coefficient of phenol ret at 610nM is 22 mM-1 cm-1
The molar extinction coefficient (also sometimes called molar absorbtivity coefficient) is a measure of how strongly a solution of a substance absorbs light (the value depends on the particular wavelength of light used). By passing light through a solution and determining how much of the light is absorbed, you can use the path length and molar extinction coefficient to determine the concentration of the solution.Look up "Beer-Lambert law" if you want details.
The molar extinction coefficient of BSA (bovine serum albumin) is approximately 43,824 M^(-1)cm^(-1) at a wavelength of 280 nm. This value is commonly used to quantify the concentration of BSA in a solution based on its absorbance at 280 nm.
Molar extinction coefficient is depend on intensity of the colour of solution.If the solution has high intensity of colour, molar extinction coefficient is high.So when considering CoCl2 and KMnO4, CoCl2 has low colour intensity. KMnO4 solution has much intense purple colour.Therefore its Molar extinction coefficient is high. By-Tharindu Chathuranga Ariyathilaka/Sri Lanka
The extinction coefficient can refer to a few different measures how strongly a distinct medium absorbs light at a particular wavelength. The two most commonly referred to are molar absorptivity (which measures absorption per molar concentration) and the mass attenuation coefficient (which measures absorption per mass density).
The molar extinction coefficient of ADP at a specific wavelength varies depending on the solvent and experimental conditions. It is typically around 8100 M-1cm-1 at 259 nm for ADP in water. Make sure to consult a reliable source or perform your own measurements for accurate values.

I am not some one of this background and so please correct me if I am wrong. I think molar extinction coefficient will be very less and according to molecular structure of any molecule (bond vibration etc..,) only some wavelengths will have reasonable absorption and for glucose those wavelenghts are 1550-1850 nm; 6450-5400 cm(-1) (first overtone) 2000-2500 nm; 4000-5000 cm(-1) (combination). These are the spectral windows in which glucose has significant absorption.
The extinction coefficient of crystal violet is approximately 89,000 M^(-1)cm^(-1) at a wavelength of 590 nm. This value indicates the molar absorptivity of crystal violet at this specific wavelength, which is commonly used for measuring the concentration of crystal violet in solution using spectrophotometry.
We would need to know the path length and the molar extinction coefficient to answer that question. If you know these, it's an extremely simple matter of Beer's Law and algebra.
Given, molar mass, coefficient ratio, molar mass, answer
Yes, using the balanced chemical equation for the reaction, you can determine the molar masses of the products by calculating the sum of the molar masses of the atoms present in the products. The stoichiometry of the reaction will determine the ratios in which the reactants react to form products.
