The data collected are shown. mass of water = W g. mass of ethanol burned = X g. temperature rise = Y ∘C. molar mass of ethanol = Zgmol−1. specific heat capacity of water = 4.2JK−1 g−1. Which expression can be used to calculate the ...experiment 1: calculating the molar mass of ethanol. Data Sheet. Table 1: Molar Mass and Water Vapor Density Data. Barometric Pressure. 1.007 atm. Mass of Flask + Foil. 120.1g. Mass of Flask + Foil + Condensed Liquid. 121.5g. Mass of Condensed Liquid. 1.4g. Volume of Flask. 348ML. Temperature of Water Bath when Vaporization Begins. 32.3 C. …The accepted value for the molar heat of combustion of ethanol is 1360 kJ mol.-1. Measure and record the mass of a burner containing ethanol. Measure 100 mL of water into a beaker and measure the temperature of the water. Place the beaker of water directly above the burner and light it. Allow the burner to heat the water for one minute, then ...Proton affinity (kJ/mol) Reference Comment; 779.4 ± 0.8: Tabrizchi and Shooshtari, 2003: T = 403-453K; Authors report only relative PAs. Absolute values are referenced here to PA(CH3COOC2H5) = 835.7 kJ/mol as listed in Hunter and Lias, 1998, although average PA(CH3COOC2H5) from the literature sources in Hunter and Lias, 1998 is 831.0 kJ/mol; …A material, substance, compound or element with a name containing, like or similar to Ethanol: Ethanol, sodium salt [C 2 H 5 ONa or C 2 H 5 NaO] weighs 868 kg/m³ (54.18747 lb/ft³) [ weight to volume | volume to weight | price | mole to volume and weight | mass and molar concentration | density] Reference (ID: 1178) 1. The heat absorbed by the water is calculated: q = mcΔT q = m c Δ T. where m = mass of water in kg, c = specific heat capacity of water ( 4.18 × 103J kg−1K−1 4.18 × 10 3 J k g - 1 K - 1, ∆ T = change in temperature (in K or ºC) The enthalpy of combustion is calculated by dividing by the mole of alcohol consumed during complete ...Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol. Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol. This is the number of moles in 100 g of water..

Compute Mass of Each Element. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in CH3OH: Molar Mass (g/mol) C (Carbon) 1 × 12.0107 = 12.0107. H (Hydrogen) 4 × 1.00794 = 4.03176. O (Oxygen)

Molar mass of ethanol - The molar mass of ethanol is the mass of ethanol (C 2 H 5 OH) that contains 6.022 × 10 23 ethanol molecules. As in Example \(\PageIndex{1}\), the molecular mass of ethanol is 46.069 amu. As in Example \(\PageIndex{1}\), the molecular mass of ethanol is 46.069 amu.
