Calculate the percent composition by mass of all the elements in Ca3(PO4)2. Determine the percent composition by mass of all elements in LiClO_3. Calculate the percent by mass of the element listed first in the formula for the compound ethanol, ...
10. Convert mass of ethanol to moles of ethanol; relate the moles of ethanol to the moles of ether produced using the stoichiometry of the balanced equation. Convert moles of ether to grams; divide the actual grams of ether (determined through the density) by the theoretical mass to ...
Calculate the molarity and mole fraction of acetone in a 1.29 m solution of acetone (CH_3COCH_3) in ethanol (C_2H_5OH). (Density of acetone = 0.788 g/cm^3; density of ethanol = 0.789 g/cm^3.) Assume t What is the solute in a solution made by mixing 10 mL of metha...
The molecular formula for ethanol is CH3CH2OH or C2H5OH. The shorthand formula is simply EtOH, which describes theethane backbonewitha hydroxyl group. The molecular formula describes the type and number of atoms of elements present in an ethanol molecule. Empirical Formula The empirical formula for ...
