There's no formula. It's 6.02 x 10^23.
Avogadro's number.
That's what defines a mole, 6.02 x 10^23 atoms of any particular substance.

What is the relationship between the chemical formula of water and volume of gas in each test tube that contains hydrogen gas and oxygen gas?
the chemical formula of water is H2O, so 2 hydrogen atoms and 1 oxygen atoms. if you have 1 mole of oxygen atoms (O2) and 2 mole of hydrogen atoms (H2) in a test tube then you will form 2 mole of water. uses avagadros number and the mole formula to find out how much of each substance you will form.
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
How many moles of He are 1.20 x 1025 atoms He?
In order to find how many Moles of He are 1.20 x 1025 atoms of He, you need to divide 1.20 x 1025 atoms by the Avagadro's number (6.022 x 1023) The answer is 19.9 moles of He.
What is the importance of molecules?
Molecules can be a very important piece of information while dealing with moles or mass. For example, one can very easily convert molecules to moles to find the mass of a substance (this needs the # of molecules of the compound/element and the chemical formula). Also, the number of molecules can find moles and atoms through different equations.
How do you calculate the moles of water?
You use the formula concentration x volume to find out the number of moles
How many moles of hydrogen are in 0.80moles of quinine?
You can figure this question out by looking up quinine to find its chemical formula. The number of moles of hydrogen will be the number of hydrogen in the chemical formula. Once you see the chemical formula is C20H24N2O2 then you know that there are 24 moles of hydrogen for every one mole of quinine.
How do you find the number of hydrogen atoms in 0.050 mol of C3H8O3?
There are 8 atoms of hydrogen in each mole of C3H8O3 therefore, there are 8 x 0.05 moles in 0.05 moles of C3H8O3. Which is 0.4 moles Using Avogadro's number, there are 6.022 x10^23 atoms per mol that is the same as 0.4 x 6.022 x10^23 = 2.41 x 10^23.
How do you find the number of moles of hydrogen there are in 3.5 moles of NH42 CO3?
The answer is 14,115 moles.
How do you find moles of acidic h atoms?
.1146g of mass of Unknown and 12.00ml of NaOH. Find the moles of acidic H atoms
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
How many moles of Na contain 7.88x1021 atoms of Na (to find moles, divide atoms by Avogadro's number)?
0.013089701
How many atoms of hydrogen and oxygen are in hydrogen peroxide?
Interesting question. Balanced equation. H2 + O2 >> H2O2 ( let's find moles and limiting reactant ) 10 O2 molecules (1 mole/6.022 X 10 ^23) = 1.66 X 10^-23 moles O2 same for H2, so one to one and reaction is driven by above moles, but use O2 for convenience. actually, as all is one to one, you get back 10 molecules H2O2 anyway 1.66 X 10^-23 X 6.022 X 10^23 = 9.99, or 10 molecules of H2O2
What is the empirical formula of a compund that breaks down into 4.12g of N and 0.88g of H?
To find the correct ratio of atoms in this compound, it is necessary to find the correct molar ratios. Nitrogen has a molar weight of 14.007 g/mol and Hydrogen has a molar mass of 1.0079 g/mol. It can be calculated then, that there are .294 moles of nitrogen and .873 moles of hydrogen. This ratio is .294 to .873 or approximately 1:3, giving a compound that is NH3, or ammonia.
What is the relationship between the chemical formula of water and volume of gas in each test tube that contains hydrogen gas and oxygen gas?
the chemical formula of water is H2O, so 2 hydrogen atoms and 1 oxygen atoms. if you have 1 mole of oxygen atoms (O2) and 2 mole of hydrogen atoms (H2) in a test tube then you will form 2 mole of water. uses avagadros number and the mole formula to find out how much of each substance you will form.
How many atoms is in 2.3 moles of gallium?
How many atoms of gallium are in 2.85 x 103 g of gallium?
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
How many moles of He are 1.20 x 1025 atoms He?
