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.

∙ 9y agoOne mole of any substance contains about 6.022 x 10^23 "particles" of that substance. In the case of water, which is H2O, we'll have about 6.022 x 10^23 molecules of water in a mole of water. But to find the number of hydrogen atoms in a mole of water, we'll have to double the number of molecules in a mole of water. The reason for this is obvious; there are two atoms of hydrogen in one molecule of water. That means there are about 2 times 6.022 x 10^23 atoms of hydrogen in that mole of water, or about 1.2088 x 10^24 atoms of hydrogen in a mole of water.

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 ========================
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 present in 2grams cholesterol?
2 grams C27H46O (1 mole C27H46O/386.638 grams)(46 mole H/1 mole C27H46O)(6.022 X 1023/1 mole H) = 1 X 1023 atoms of hydrogen =====================
How many moles are in 2.35g are in water?
2.35 grams water (1 mole H2O/18.016 grams) = 0.130 moles water ===============
How many moles of hydrogen gas could be produced by the complete decomposition of 1 mole of water?
Since a water molecule, H2O, has exactly the same quantity of hydrogen atoms as a hydrogen molecule, H2, it follows that one mole of water can be decomposed into one mole of hydrogen gas.
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 hydrogen atoms are in 738 grams of water?
Quite a few! 738 grams water (1 mole H2O/18.016 grams)(2 mole H/1 mole H2O)(6.022 X 10^23/1 mole H) = 4.93 X 10^25 atoms of hydrogen
How many GRAMS of hydrogen are present in 2.08 moles of water?
2.08 moles H2O (2 moles H/1 mole H2O)(1.008 grams H/1 mole H) = 4.19 grams of hydrogen ===================
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 ========================
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 many grams are in one mole of hydrogen peroxide?
36 grams
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 grams of hydrogen are there in 150 g of ammonia?
150 grams NH3 (1 mole NH3/17.034 grams)(3 mole H/1 mole NH3)(1.008 grams/1 mole H)= 26.6 grams hydrogen=================17 g of ammonia has 3 g of hydrogen.So 150 g of ammonia will have 26.5 g of hydrogen
How many hydrogen atoms are in 5.839 grams of c8h8?
5.839 grams C8H8 ( 1 mole C8H8/104.144 grams)(8 mole H/1 mole C8H8)(6.022 X 1023/1 mole H) = 2.701 X 1023 atoms of hydrogen --------------------------------------------
How many atoms of hydrogen 31 grams in CH2O?
31 grams CH2O (1 mole CH2O/30.026 grams)(2 mole H/1 mole CH2O)(6.022 X 1023/1 mole H) = 1.2 X 1024 atoms of hydrogen =======================
How many grams of water can be prepared from 5moles of hydrogen at standard conditions?
Balanced equation. 2H2 + O2 --> 2H2O 5 moles H2 (2 moles H2O/2 mole H2)(18.016 grams/1 mole H2O) = 90 grams of water ===============
How many grams of water could be made from 5.0 mol H2 and 3.0 mol O2?
The formula for Oxygen gas is O2, and the formula for water is H2O. Each molecule of Oxygen gas can produce 2 molecules of water (with enough Hydrogen, of course). So, 2.5 moles of Oxygen gas would be required to produce 5.0 moles of water.
