one mole of any element is equals to its gam(Gram Atomic Mass)
and one mole of any molecule is also equals to that molecules gram Atomic Mass.
Lets calculate the gram molecular mass of water :
h2o = 2 hydrogen atoms, 1 oxygen atom
= 2 hydrogen x 1g (gram atomic mass of hydrogen) + 1 oxygen x 16g (gram atomic mass of oxygen)
= 2 + 16
= 18g
Therefore 1 mole of water contains 18grams.

∙ 13y agoTo determine this, we must first find the molar mass of H2O which is 18.01528 g/mol. (Take the atomic mass of H X2 since 2 H atoms present, + atomic mass of O).
Then we must divide mass by molar mass.
So, n= 1.00g/18.01528g/mol
n= 0.055508 mol
earlier responses gave answer to fewer decimal points, users should give number of significant figures relevant to their application

∙ 12y agoThe molar mass of a water molecule is 18.02 grams per mole. If given the mass of water, you can use this molar mass as a conversion factor:
1g H2O x (1mol H2O / 18.02g H2O) = 0.0555mol H2O

∙ 13y agoSimple answer? 18g
A mole is the formula mass in grams.
Mass of H = approx 1
Mass of O = approx 16

How many grams are in one mole of Bromine trifluoride?
137g
Is one mole of cadmium heavier than one mole of gold?
yes, one mole of cadmium is 112 grams, one mole of gold is only 2 grams.
How many mole of H atoms in 1 mole of H2O2?
17.32 moles H2O (2 moles H/1 mole H2O) = 34.64 moles hydrogen
How many moles of water are needed to react with 2.2 moles of Li2O?
Because 2Li + O2 --> Li2O2 moles Li produces 1 mole Li2O3.04Li + --> 1.52 O2 --> 1.52 Li2O1.52 moles Li2O arw formed.
What is the number of moles in 4.50 grams of H2O?
There are four molecules of water in 4H2O. One molecule of water is written as H2O. The subscript 2 tells you that there are two H(hydrogen) atoms. Since there is no subscript after the O there is one O(oxygen) atom. Now back to 4H2O. The coefficient 4 tells you there are four molecules of H2O. Therefore there are eight H(hydrogen) atoms and four O(oxygen) atoms.
How many grams are in one mole of water using 4 significant figures?
1 mole H2O = 18.02g --- water is H2O ... 2 x 1.008 + 1 x 15.996 = 18.012 g/mole = 18.01 grams
How many moles are present in 500.00 g of H2O?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams500.0 grams H2O / (18.0 grams) = 27.8 moles H2O
How many moles are in 35.1 grams of water?
To teach you how to do this problem: 1. Look at the Periodic Table. O =16 grams/mole, H =1.01 grams/mole 2. Calculate the Molecular Weight of Water. 1*O + 2*H: 16+2.02=18.02g/mole 3. Divide the mass of what you have by the Molecular Weight: 35.1g H2O/(18.02 g H2O/mole H2O) 4. The units g H2O cancel leaving you with mole H2O. 5. 35.1 grams H2O= 1.95 moles H2O
How many moles of hydrogen gas would be needed to react with excess carbon dioxide to produce 19.1 moles of water vapor?
CO2 + H2 <-> CO + H2O all one to one ( I assume that 99.1 is grams. Always units!!!! ) 99.1 grams H2O (1 mole H2O/18.016 grams)(1 mole H2/1 mole H2O) = 5.50 moles of hydrogen gas needed If that was 99.1 moles water vapor then it would take 99.1 moles hydrogen gas at a one to one ratio.
6.00 g water contains how many moles?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O= 18.0 grams.417 grams H2O / (18.0 grams) = .0232 moles H2O
How many oxygen atoms are present in a water sample containing 4.5 x 1023 hydrogen atoms?
You must mean; how many grams of O ( one atom oxygen ) 1.23 X 10^24 molecules H2O (1 mole H2O/6.022 X 10^23)(1 mole O/1 mole H2O)(16 grams/1 mole O) = 32.7 grams of oxygen

How many moles of H2O are product from reaction of 355 g of O2?
Balanced equation. 2H2 + O2 -> 2H2O 355 grams O2/32 grams = 11.1 moles O2 check for limiting reactant 11.1 moles O2 (2 mole H2/1 mole O2) = 22.2 mole H2 and H2 has no where near that many moles, so limits and drives reaction so, as they are one to one...... 22.2 moles of H2O are produced
How many moles are there in 235 grams of H2O?
For this you need the atomic (molecular) mass of H2O. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. H2O=18.0 grams235 grams H2O / (18.0 grams) = 13.1 moles H2O
How many moles of hydrogen atoms are present in 25 grams of water?
For this you need the atomic (molecular) mass of H2O. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. H2O= 18.0 grams2.5 moles H2O × (18.0 grams) = 45.0 grams H2O
