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.

How many grams of h20 are equivalent to 4 mole of h20?
Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
How many grams in one mole of silicon?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Selenium's atomic mass is 78.96 grams.
How many grams are in one mole of Bromine trifluoride?
The molar mass of Bromine trifluoride is approximately 126.893 g/mol. Therefore, one mole of Bromine trifluoride contains 126.893 grams.
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 half a mole of NaCl?
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.Na- 23.0Cl- 35.5NaCl- 58.5 grams in one mole
How many grams of h20 are equivalent to 4 mole of h20?
Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
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 grams are in one mole of C5H12?
The molar mass of C5H12 is 72 grams/mole.
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 grams of pseudoephedrine are in one mole?
The answer is 165,23 grams.
How many grams in one mole of ice?
One mole of ice, which is the same as one mole of water, has a molar mass of approximately 18 grams/mol.
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 are in one mole of hydrogen peroxide?
36 grams
How many grams are in one mole of xenon?
The molar mass of xenon is approximately 131.3 grams per mole. Therefore, one mole of xenon contains 131.3 grams.
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.
