What is the constituent element of propylene glycol?
Ethylene glycol (IUPAC name: ethane-1,2-diol; Chemical formula C2H6O2) is an organic compound widely used as an automotive antifreeze and a precursor to polymers. In its pure form, it is an odorless, colorless, syrupy, sweet-tasting liquid. Ethylene glycol is toxic, and ingestion can result in death.
How do you find the lethal dose in moles not kg of ethylene glycol?
The EPA reports that 120cc is the lethal dose. Regular EG (C2H6O2) has a density of 1.115 g/cc @ 20 deg C (68 deg F) and 1.085 g/cc @ 60 deg C (140 deg F). Thus at room temp, 133.8 g of liquid EG is lethal. The molecular weight is 62.07 g/g-mol. So, to answer your question, 2.156 g-mole of pure, liquid EG at room temperature is lethal.
How many atoms are in Iron III acetate?
The formula for the formula unit of anhydrous iron (III) acetate is Fe(C2H6O2)3. Tally the atoms as follows: Multiply the subscript within parentheses by the subscript after the parentheses to obtain 6 carbon atoms, 18 hydrogen atoms, and six oxygen atoms; add the one atom of iron (implied by lack of any subscript immediately following it); the total is 31 atoms.
What is the freezing point of a solution prepared from 50.0 g ethylene glycol and 85.0 g H2O Kf of water is 1.86 Celsius?
50g C2H6O2(1 mol C2H6O2/62g C2H6O2)= .81mol C2H6O2 (.81mol C2H6O2/.085kg H2O)=9.53m Kf=1.86 C/m delta t=(1.86 C /m)(9.53m)= 17.7 C t=(0 C-17.7C)=-17.7 C is the freezing point of the solution.
The density of a 20 percent by mass ethylene glycol solution in water is 1.03gml Find the molarity of the solution?
(0.23)(1.04g/mL)(1000mL/L)(1 mol C2H6O2/62g C2H6O2) = 3.86 M
What elements is ethylene glycol made up of?
The chemical formula for ethylene glycol is C2H6O2.
What is the classification for C2H6O2?
The classification for C2H6O2 is a molecular compound. This is the chemical formula for ethylene glycol which has non-dissociating bonds.
What is the molecular formula of ethylene glycol if mass is 62amu?
C2h6o2
What is the Empirical formula for Ethanol?
NOT: C9h17o3 but HO-CH2-CH2-OH, C2H6O2 Ethylene glycol is 1,2-ethanediol:
How many grams of water are in the solution of 6.20 g of C2H6O2 if freezing point is -0.372 degrees Celsius?
How_many_grams_of_water_are_in_the_solution_of_6.20_g_of_C2H6O2_if_freezing_point_is_-0.372_degrees_Celsius
How many grams of ethylene glycol automobile antifreeze C2H6O2 dissolved in 3.80kg of water is needed to lower the freezing point of water in an automobile radiator to 21.0C?
None. The freezing point of pure water is already lower than that.
How many hydrogen atoms are in six molecules of ethylene glycol C2H6O2?
36
What is pH of ethylene glycol?
Molecular formula is C2H6O2 Maybe pH is 7. I measure the PH of ethylene glycol myself with az 8686 PH meter. The number that i saw was 8. I thinck its because of hydroxyl group(OH) in its Molecular formula(HOCH2CH2OH=C2H6O2).
How many hydrogen atoms are in six molecules of ethylene glycol HOCH2CH2OH?
The chemical formula for ethylene glycol is C2H6O2, so in 6 molecules there would be 36 atoms of hydrogen
What are true the vapor pressure of 1 m ethylene glycol C2H6O2 is the same as the vapor pressure of 1 m kCI where the solvent is water is it true or false?
False. as the number of ions in solution are different for both.
