How many grams of ethanol in 1 mole
Web3 jan. 2024 · Moles allow you to directly read weight from the periodic table (e.g., 1 mole of N₂ is 28 g or 1 mole of NaCl is 58.5 g). We can link the number of entities X in a specified sample – N (X), to the moles of X in the same sample – n (X), with the relation: n (X) = N (X)/NA. N (X) is dimensionless, and n (X) has the SI unit mole. What is molarity? WebExample #2:A solution is prepared by mixing 25.0 g of water, H2O, and 25.0 g of ethanol, C2H5OH. Determine the mole fractions of each substance. Solution: 1) Determine the moles of each substance: H2O ---> 25.0 g / 18.0 g/mol = 1.34 mol C2H5OH ---> 25.0 g / 46.07 g/mol = 0.543 mol 2) Determine mole fractions:
