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.

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.


If a small rock is two grams how many small rocks would it take to equal the mass of the larger rock that weighed 3 kilograms?

To find out how many small rocks are needed to equal the mass of the larger rock, we first convert the mass of the larger rock from kilograms to grams: 3 kilograms = 3000 grams. Since each small rock weighs 2 grams, to find the number of small rocks needed, we divide the mass of the larger rock by the weight of each small rock: 3000 grams / 2 grams per small rock = 1500 small rocks. Therefore, it would take 1500 small rocks to equal the mass of the larger rock weighing 3 kilograms.

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


How do you convert 1amu into grams?

The atomic mass unit (amu) is defined to be exactly 1/12 of the mass of a C-12 atom (Not a mole of carbon atoms...) Therefore 1 C-12 atom has a mass of exactly 12.00000000 amu. Also, therefore, 1 amu is a very small unit of mass - specifically 1amu = 1.66053X10^-24 grams. 1.00 mole of C-12 atoms has a mass of 12.0000000 grams!

What is 0.25 of a pound?

0.25 of a pound is equivalent to a quarter of a pound, which is 4 ounces. To convert it into grams, 0.25 pounds is approximately 113.4 grams. Therefore, 0.25 pounds is a small weight often used in cooking and measuring ingredients.


A mole of moles would have a mass how many times greater than the mass of the earth?

The eastern mole weighs about 75 grams individually. A mole of these moles would weigh 4.52 E22 kilograms. The mass of the Earth is estimated at 5.97219 E 24 kilograms. This reduces to 4520/597219 or .007568, which is .7568 percent.
