WebNov 8, 2024 · v/v % = 5.0 ml alcohol / 75 ml solution x 100% = 6.7% ethanol solution, by volume. How to Calculate Mole Fraction of a Solution Mole fraction or molar fraction is the number of moles of one component of a solution divided by the total number of moles of all chemical species. WebFeb 28, 2024 · Using the equation for a line (Y 2 - Y 1 )/ (X 2 - X 1) = (0.41-0.27)/ (0.3-0.2) = 0.14/0.1 = 1.4 is the slope of the line. 4. Divide the slope of the line by the path length (depth of the cuvette) to calculate molar absorptivity. The final step to calculating molar absorptivity with data points is to divide by the path length. god of war germanos
