Mole of hydrogen vs mole of uranium?
A mole of hydrogen contains Avogadro's number of hydrogen atoms, while a mole of uranium contains Avogadro's number of uranium atoms. Hydrogen is a light element with a low atomic weight, while uranium is a heavy element with a high atomic weight. This means that a mole of hydrogen weighs much less than a mole of uranium.
How many hydrogen atoms present in 2grams cholesterol?
To find the number of hydrogen atoms in 2 grams of cholesterol, you need to first calculate the molar mass of cholesterol (about 386 g/mol) and then divide the given mass by the molar mass to find the number of moles. Next, use the molecular formula of cholesterol (C27H46O) to determine the number of hydrogen atoms in one mole of cholesterol. Finally, multiply this number by the number of moles to find the total number of hydrogen atoms present in 2 grams of cholesterol.
How many hydrogen atoms are in 5.839 grams of c8h8?
To find the number of hydrogen atoms in 5.839 grams of C8H8, first calculate the molar mass of C8H8, which is 104 g/mol. Next, find the number of moles of C8H8 in 5.839 grams using the molar mass. Since there are 8 hydrogen atoms per molecule of C8H8, multiply the number of moles by 8 to get the number of hydrogen atoms.
What does concentration of hydrogen ions mean?
it is the number of mole in hydrogen per cubic decimeyer
How many hydrogen atoms are in 738 grams of water?
To find the number of hydrogen atoms, we need to first determine the number of water molecules in 738 grams of water. Then, using the molecular formula of water (H2O), we know that each water molecule contains 2 hydrogen atoms. Finally, we can calculate the total number of hydrogen atoms by multiplying the number of water molecules by 2.
What is the number of hydrogen atoms in 90 amu of ethane?
To find the number of hydrogen atoms in 90 amu of ethane (C2H6), use the molar mass of ethane to determine the number of moles present. Next, use the molecular formula of ethane to calculate the number of hydrogen atoms in one mole, and then multiply by the number of moles present to find the total number of hydrogen atoms.
How many atoms of hydrogen are there in the mole of H2O molecules?
In one mole of water (H2O), there are 2 moles of hydrogen atoms (H) due to the formula H2O having 2 hydrogen atoms. Since 1 mole of hydrogen contains Avogadro's number of atoms (6.022 x 10^23), in a mole of water there are 2 times Avogadro's number of hydrogen atoms, which equals 1.2044 x 10^24 atoms.
How many atoms of hydrogen are in 3.4 grams of hydrogen peroxide?
To calculate the number of atoms in 3.4 grams of hydrogen peroxide, you first convert the grams to moles using the molar mass of hydrogen peroxide. Then, you use Avogadro's number to convert moles to atoms. There are approximately 6.022 x 10^23 atoms in 1 mole of a substance.
What is the total number of moles of hydrogen in 1 mole of NH4 2HPO4?
In NH4 2HPO4, there are 4 moles of hydrogen atoms present. Since each mole of hydrogen molecule (H2) contains 2 moles of hydrogen atoms, there are a total of 2 moles of hydrogen molecules in 1 mole of NH4 2HPO4.
How many atoms of hydrogen are present in 1.5 lb of hydrogen peroxide which is 5.93 percent hydrogen. 1 lb equals 454 grams.?
First, calculate the total weight of hydrogen in 1.5 lb of hydrogen peroxide: 1.5 lb * 454 g/lb * 0.0593 = 128.97 g of H2O2 Then, convert this weight to the number of moles of hydrogen: 128.97 g / 34.0147 g/mol = 3.79 moles of H2O2 Since each mole of H2O2 has 2 moles of hydrogen atoms, there are 3.79 * 2 = 7.58 moles of hydrogen atoms. Finally, calculate the number of atoms: 7.58 moles * 6.022 x 10^23 atoms/mol = 4.56 x 10^24 atoms of hydrogen.
How many grams are in a mole of hydrogen chloride?
Trick question. Hydrogen is a diatomic molecule; it travels around with a buddy as H2 and not as a single atom. This is generally true of all gases except the inert gases. By definition, a mole of anything has 6.022 x 1023 "units" of that stuff. (That's Avogadro's number.) The "stuff" is the atoms or the molecules of that "stuff" and it can be thought of in terms of the "reaction units" of that stuff. We do not have H2 + O = H2O. We have 2H2 + O2 = 2H2O because oxygen is diatomic like hydrogen. The "reaction units" of hydrogen and oxygen are H2 and O2 respectively. Now the answer will appear. A mole of hydrogen is 6.022 x 1023 units of hydrogen which will be 6.022 x 1023 molecules of hydrogen which will be (6.022 x 1023 times 2) atoms of hydrogen which will be 1.204 x 1024 atoms of hydrogen.
What is the relationship between avogadros number and one mole of any substance?
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
