26 июл. 2019 г. · The mol fraction is moles solute per mole solvent. In your case, that means you have .2 moles of solute per 1 mole of benzene. |
12 июн. 2024 г. · To calculate the molality, multiply the mole fraction by 1000 divided by the molar mass of the solvent, then divide by 1 minus the mole fraction ... |
13 июн. 2018 г. · Convert 0.1538 mole fraction of propanol (C3H8O) in water to molality. 4sig figs. Then convert the same mole fraction to percent by mass. |
The relationship between molality m and mole fraction XA of the solvent is:A. m = XA /1 XA ×1000B. m =1 t u / YOÁ1000C. m =1 X A / XA ×1000/ XBD. m = X A /1 ... |
9 янв. 2020 г. · The expression for the molality is XA×1000(1−XA)mB=m. For two different mole fractions of A, i.e. 1/2 and 1/3, the expression becomes, 12×1000(1 ... |
20 янв. 2019 г. · Note that you have to convert molality expressed in molkg−1 before plugging in the value: 1 m=1 molkg−1=1⋅10−3 molg−1. |
Hint: We know the mathematical formula for Molality and Mole fraction. Use these formulas to calculate. Here urea is the solute and water are the solvent. |
