How many grams of hydrogen are in 25.0g of water?
25x(2/18)=2.78g of hydrogen 25x(16/18)=22.22g of oxygen
How many hydrogen atoms are in 871 grams of water?
Quite a few! 871 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 1023/1 mole H) = 5.82 X 1025 atoms of hydrogen ========================
In grams which is the most accurate description of the mass ratio of hydrogen to oxygen when they chemically combine to form water?
When hydrogen and oxygen chemically combine to form water (H₂O), the mass ratio of hydrogen to oxygen is approximately 1:8. This is based on the molar masses, where hydrogen has a molar mass of about 1 gram per mole and oxygen about 16 grams per mole. Therefore, for every 2 grams of hydrogen, there are about 16 grams of oxygen in water, maintaining that 1:8 ratio.
How many grams of H2O are necessary to weigh out 1 mole of H2O?
HCN is hydrocyanic acid and contains no oxygen, so producing it doesn't require oxygen. So zero grams.
Which gas has the lowest mass per mole?
Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
Does a mole of water weigh the same as a mole of hydrogen?
No. A mole of hydrogen (in its normal form) weighs 2 grams. A mole of water weighs 18 grams.

How many GRAMS of hydrogen are present in 2.08 moles of water?
In 1 mole of water (H2O), there are 2 moles of hydrogen (H). This means that in 2.08 moles of water, there are 2.08 x 2 = 4.16 moles of hydrogen. To convert moles to grams, we use the molar mass of hydrogen: 4.16 moles x 1.01 g/mol = 4.22 grams of hydrogen.
How many grams are in one mole of hydrogen peroxide?
36 grams
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.
How many atoms of hydrogen is present in 0.5 gm mole of water?
I assume you mean 0.5 grams water. 0.5 grams water (1 mole H2O/18.016 grams)(2 moles H/1 mole H2O)(6.022 X 10^23/1 mole H) = 3.3 X 10^22 atoms of hydrogen
How much hydrogen in 1 litre of water?
One liter of water (H₂O) contains about 111 grams of hydrogen. Since water is composed of two hydrogen atoms and one oxygen atom, the molecular weight of water is approximately 18 grams per mole, with hydrogen contributing about 2 grams per mole. Therefore, in one liter of water, which is roughly 55.5 moles, there is a significant amount of hydrogen.
How many grams of water can be prepared from 5moles of hydrogen at standard conditions?
At standard conditions, 1 mole of hydrogen reacts with 0.5 moles of oxygen to form 1 mole of water. Therefore, to form 5 moles of water, you will need 5 moles of hydrogen and 2.5 moles of oxygen. The molar mass of water is approximately 18 g/mol, so 5 moles of water would weigh 90 grams.
How many grams of H2O do you need to weigh out to have 1 mole of H2O?
To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
How many atoms of oxygen are there in 13 grams of water?
There are 7.24 x 10^23 atoms of oxygen in 13 grams of water. This calculation is based on the molar mass of water (18.015 g/mol) and the fact that each water molecule contains two hydrogen atoms and one oxygen atom.
How many grams in one mole?
That depends on the substance, and on whether you are considering atoms ore molecules. One mole has as many grams as the atomic or molecular mass of the substance. For example, one mole of atomic hydrogen has 1 gram; one mole of molecular hydrogen has 2 grams, one mole water has 18 grams, etc., since those numbers are the corresponding atomic or molecular masses.
