How can one determine the chemical formula from percent composition?
To determine the chemical formula from percent composition, you need to convert the percent composition of each element into moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. Finally, use this ratio to write the chemical formula.
How many moles of hydrogen are present in 3 moles of methane?
Methane (CH4) has four atoms of hydrogen per molecule. If there are 3 moles of methane, then there are 12 moles of hydrogen.
How many hydrogen atoms are present in 2 moles of ch4?
One molecule has four H atoms.So two moles have 8 moles
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 88.1 moles of water vapor?
The balanced chemical equation for the reaction is 2H2 + CO2 -> 2H2O. This means that 2 moles of hydrogen gas react with 1 mole of carbon dioxide to produce 2 moles of water vapor. Therefore, to produce 88.1 moles of water vapor, 44.05 moles of hydrogen gas would be needed.
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 53.6 moles of water vapor?
This is the Sabatier process and is usually in need of high temperature and a metallic catalyst. So, balanced equation. CO2 + 4H2 -> CH4 + 2H2O As said, hydrogen is in excess, so CO2 is limiting and drives the reaction. One to one 36.6 moles CO2 (1 mole CH4/1 mole CO2) = 36.6 moles CH4 produced in this reaction -------------------------------------------------------
How many moles of carbon and hydrogen are there in 5 moles of octane?
In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).

How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 30.6 moles of water vapor?
CO2 + H2 -> CO + H2O one to one here 30.6 moles H2O (1 mole H2/1 mole H2O) = 30.6 moles Hydrogen gas needed
How many atoms of hydrogen are in 0.180 moles of carbon hydroxide?
To find the number of atoms of hydrogen in a compound, you need to look at the chemical formula. In carbon hydroxide (CHO), there are 1 atom of hydrogen for each carbon and oxygen atom. In this case, there are 0.180 moles of CHO, so there are 0.180 moles of hydrogen atoms as well. To convert moles to atoms, you can use Avogadro's number (6.022 x 10^23) to find that there are approximately 1.08 x 10^23 atoms of hydrogen in 0.180 moles of carbon hydroxide.

How many moles of hydrogen cyanide would be produced from the complete reaction of 10 moles of oxygen gas?
Absolutely none, as there is no oxygen in hydrogen cyanide. Its formula is HCN--one atom each of hydrogen, carbon and nitrogen.
What is the empirical formula of a molecule containing 24 percent carbon C 6 percent hydrogen H and 70 percent chlorine Cl?
CH3Cl
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 53.6 moles of water vapor?
This is the Sabatier process and is usually in need of high temperature and a metallic catalyst. So, balanced equation. CO2 + 4H2 -> CH4 + 2H2O As said, hydrogen is in excess, so CO2 is limiting and drives the reaction. One to one 36.6 moles CO2 (1 mole CH4/1 mole CO2) = 36.6 moles CH4 produced in this reaction -------------------------------------------------------
How many atoms of hydrogens are in 3 moles of CH4?
There are 12 atoms of hydrogen in 3 moles of CH4. CH4 consists of one carbon atom and four hydrogen atoms. Since each mole of CH4 has 4 hydrogen atoms, 3 moles would have 3 * 4 = 12 hydrogen atoms in total.
How can one determine the empirical formula from percent composition?
To determine the empirical formula from percent composition, first convert the percentages to grams. Then divide the grams of each element by its molar mass to find the moles. Finally, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio, which represents the empirical formula.
