Carbon (C) has a atomic weight of 12 gr/mol Hydrogen (H) has an atomic weight of 1 gr/mol Therefore C2H4 has a molecular weight of 28 gr/mol (2x12 + 4x1) By dividing 86.2 grams by 28 gr/mol, you get 3.59 moles.

Would you measure a penguin in kg or grams?
Kilograms because grams are to small for a penguin
How many grams are in 0.169 pounds?
0.169 lbs. = 76.65711 grams; grams are very small, they are used to measure medicine.
How many pounds go into grams?
Grams are very small compared to pounds, there are 454grams in 1 pound.
What is 5.1 kilograms converted into grams?
You can't get 5 gram to pound and kilograms together as it is too small and completely different units unlike pounds and ounces. Five grams would equal to 0.005 kilograms. 5 grams would equal to 0.0110231 pounds.
How much is 65 milligrams of salt?
0.065 grams or a small amount
The body can absorb up to 120 grams of carbohydrate per hour from the small intestine. If we assume this is all in the form of glucose how many moles of glucose have been absorbed?
0.67 moles of C6H12O6
How do you convert from moles to gram?
You must first find the molar mass of the element or compound. Use the periodic table (see the link to the left of the answer). If the chemical is an element, just read off the atomic mass from the periodic table. If it is a compound, you must know the molecular formula, and then you find the total molar mass of the compound by adding up the atomic masses of each atom in the compound. The unit of the molar mass will be in grams per moles (g/mole)Once you have the molar mass, you can easily convert from grams to moles, and also from moles to grams.Number of moles = (# of grams) / (molar mass)Number of grams = (# of moles) * (molar mass)Here are a two examples:Example 1:How many moles are in 5 grams of O2?The molar mass of O2 = 16.00 g/mole x 2 (for 2 atoms of oxygen) or 32.00 g/mole.5 g of O2 / (32 g/mole) = 0.15625 molesExample 2:How many grams does 4 moles of NH3 weigh?The molar mass of NH3 = 14.01 + (3 * 1.01) = 17.04 g/mole4 moles * 17.04 g/mole = 68.16 grams Grams in a MoleIn chemistry a mole is considered to be Avogadro's number (6.02 x 1023)of molecules (or atoms) of a substance - so depending on the density of the substance, the mass of that amount of the substance could vary widely.One mole of hydrogen, for example, would have a different mass than one mole of lead. The question compares two different measurements of a given substance, rather like asking "how heavy is a gallon?". The question becomes "A gallon of what"?*On the other hand, the Eastern Mole (Scalopus aquaticus) a small, burrowing mammal, weighs between 54 and 99 grams at adult size.To convert grams to moles simply multiply the molar mass by the number of moles.
What are golden moles predators?
Moles eat small invertebrates such as grubs and earthworms found in the soil. They will also catch and eat small mice.
Are moles dangerous to dogs?
can a mole in my yard hurt my small dog/
What are some small animals?
bird are small animals and moles, and hamsters
Do Italian moles have eyes?
Italian moles do have eyes. All moles have very small eyes and, despite popular myth, are not creatures of blindness.
Do raccons dig for moles?
Yes, raccoons will occasionally eat moles as well as other small mammals.
What is the molecular formula of fructose with C 40 percent H 6.72 percent O 53.28 percent?
We assume 100 grams and turn those percentages into grams and find moles of species. 40 grams carbon (1 mole C/12.01 grams) = 3.33 moles C 6.72 grams hydrogen (1 mole H/1.008 grams) = 6.67 moles H 53.28 grams oxygen (1 mole O/16 grams) = 3.33 The smallest mole number is 1, so we have two small numbers. Divide the large number by the small. 6.67/3/33 = 2 so.............. CH2O is the empirical formula. You did not state that you had a quantity of this compound ( such as 60 grams, or whatever ), so the molecular formula can not be found from this info. C6H12O6 is of course the molecular formula. To find the molecular formula you need a mass of the compound aside from the simple percentages. Then you find, as we have done, the empirical formula. you divide the mass given by the mass of the empirical formula and then take that quotient and multiply it times the empirical formula. In this case (CH2O) * 6 = C6H12O6, the molecular formula
Is grams big or small?
Small
Does oxidation affect the mass of a penny?
However, the surface oxide layer is not very thick, so in practical terms the difference is going to be small (and since the total mass of a current US penny is 2.5 grams and only 2.5% of that is copper, even if every bit of copper were totally oxidized we're talking about a mass difference of well under 1%).
Is 100000 hydrogen molecules a lot or is it a small amount?
100000 atoms hydrogen (1 mole H/6.022 X 10^23) = 1.66 X 10^-19 moles H * 1.008 grams = 1.67 X 10^-19 grams As you can see this is a minuscule amount of hydrogen.
Is a small box of rasins a grams or a kg?
grams
