Q. Calculate the mass of compound (molar mass = 256gmol−1) to be dissolved in 75g of benzene to lower its freezing point by 0.48K(Kf=5.12Kkgmol−1). Q. When 0.9g of a nonelectrolyte was dissolved in 87.9g of benzene, the boiling point of benzene was raised by 0.25 degree...
Learn how to calculate the percentage of a number, marks using simple steps and examples. Also, get the formulas to calculate the percentage difference between numbers here at BYJU’S.
Convert the percentage of abundance to decimal form by dividing by 100 (In your situation, they've already done that work for us, so we can skip this step. Multiply the atomic mass of that isotope by the abundance in decimal form Once we have done those two steps, we add up all the ...
To find the molecular formula of caffeine based on its percentage composition and given mass, we can follow these steps:Step 1: Convert percentages to grams Assuming we have 100 g of caffeine, we can directly convert the percen
Calculate the mole fraction of a compound in a vapor using the formula y = (ά * x) / {1 + (ά -1) * x}, where "ά" is the relative volatility, "x" is the mole fraction of the substance in the liquid and "y" is the mole fraction of the substance in the vapor. This...
