What molecules contains the most moles of carbon atoms per mole of the compound ascorbic acid glycerinor vanillin?

Vanillin contains the most moles of carbon atoms per mole of the compound. Vanillin has a chemical formula of C8H8O3, ascorbic acid has C6H8O6, and glycerin has C3H8O3. Therefore, vanillin has 8 moles of carbon atoms per mole of the compound, compared to 6 moles in ascorbic acid and 3 moles in glycerin.


Which statement shows how to correctly convert from the mass of a compound in grams to the amount of that compound in moles?

To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.


How many molecules of water in 877 moles?

1 mole of any compound or element contains Avogadros Number (6.023 X 1023) molecules or atoms So 877 moles contains 877 X (6.023 X 1023) = 5.282 X 1026


How can one determine the empirical formula from moles in a chemical compound?

To determine the empirical formula from moles in a chemical compound, you first need to find the moles of each element present in the compound. Then, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.


Empirical formula for a compound that contains 32.2 percent Ca and 67.8 percent N by mass?

Assume the compound has a molar mass of 100 grams, from the information given, 32.2 grams is Calcium and 67.8 grams is Nitrogen.You then find the moles of each, which would be moles of Ca and moles of N.Dividing the two moles gives you the mole fraction: which we approximate to 6. This means that for every 1 mole of Ca, there are 6 moles of N, thus the answer is

What is the molar mass of the nonelectrolyte compound if a 4.305 g sample of it is dissolved in 105 g of water?

To find the molar mass of the nonelectrolyte compound, we need to use the formula: Molar mass (mass of compound / moles of compound) First, we need to find the moles of the compound by using the formula: moles mass / molar mass Given that the mass of the compound is 4.305 g and it is dissolved in 105 g of water, we can calculate the moles of the compound. Next, we can find the molar mass of the compound by rearranging the formula: Molar mass mass / moles By plugging in the values, we can calculate the molar mass of the nonelectrolyte compound.


How many moles of fluorine in 3 moles of borontrifluoride?

Boron trifluoride is BF3. So each mole of BF3 contains 1 moles of boron (B) and 3 moles of fluorine (F). Thus, 3 moles of BF3 contains NINE moles of fluorine.


How many moles of the element oxygen are in 4.00 moles of the compound K2Cr2O7?

The formula means, among other things, that there are 7 atoms of oxygen in each mole of the compound. Therefore, in 4.00 moles of the compound, there are 28.00 moles of oxygen atoms. Elemental oxygen usually is diatomic, so that there would be the equivalent of 14 moles of diatomic elemental oxygen.


How do you find the number of moles of hydrogen there are in 3.5 moles of NH42 CO3?

To find the number of moles of hydrogen in 3.5 moles of (NH4)2CO3, first identify the stoichiometry of the compound. In (NH4)2CO3, there are two moles of hydrogen per mole of compound. Therefore, in 3.5 moles of (NH4)2CO3, there would be 2 * 3.5 = 7 moles of hydrogen.
