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 of water are made from complete reaction of 2.2 moles of oxygen gas with hydrogen gas?
The balanced chemical equation for the reaction between oxygen and hydrogen is2H2 + 02 -> 2H2OThus 2.2 moles of oxygen reacts with 4.4 moles of hydrogen to form 4.4 moles of steam (water in gaseous state).The mass of H2O obtained is thus 4.4 x 18.0 = 79.2g.
How many grams of KCl will dissolve in 100 g of water at 50 degrees Celsius?
100 g water dissolve 45,8 g potassium chloride at 50 o 0C.
NaHCO3 is the active ingredient in baking soda. How many grams of oxygen are in 0.53 g of NaHCO3?
There are 0.47 grams of oxygen in 0.53 grams of NaHCO3.
The molar mass of water is 18.0gmol how many moles of water are represented by 1.78g?
1 mole of water is equal to 18.02 grams. H = 2 * 1.01 g = 2.02 g O = 1 * 16.00 g = 16.00 g Total = 18.02 g 1.8 g H2O * (1 mol H2O/18.02 g H2O) = 0.099889 mol H2O There are about 9.99*10-2 moles in 1.8 grams of water.
How many grams of propane did you burn if o.56 grams of water were produced?

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.
How many grams of hydrogen must be added to 800 grams of oxygen to produce 900 grams of water?
For the reaction 2H₂ + O₂ → 2H₂O, we know that the molar ratio of H₂ to O₂ is 2:1. To produce 900 grams of water, we need 450 grams of hydrogen (900g / 2). Therefore, we need to add 450 grams of hydrogen to 800 grams of oxygen to produce 900 grams of water.
How many gram of water is equal to 2.2 mol of water?
2.2 mol water = 2.2 (mol) * 18 (g/mol) water = 39.6 (mol*g/mol) = 40 g18 g/mol = mol mass of H2O = 2*H + 1*O = (2*1 + 16) g/mol
How many fat grams in McDonald's filet o fish sandwich?
One McDonald's Filet-O-Fish has 400 calories and 18 grams of fat in it.
How many grams of H 2O will be produced if 750 grams of Fe are produced?
In the reaction of Fe with H₂O to produce FeO and H₂, the ratio is 3 moles of H₂O for every 1 mole of Fe. Since the molar mass of Fe is 56 g/mol and that of H₂O is 18 g/mol, we use these values to find that 750 grams of Fe will produce 750 * (3 * 18 / 56) = 857.14 grams of H₂O.
How many grams of glucose will be formed when 22G of carbon dioxide reacts with 9G of water to make 16G of oxygen?
To determine the grams of glucose formed, we can use the balanced equation for photosynthesis: 6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂. From the equation, 6 grams of carbon dioxide and 6 grams of water produce 1 gram of glucose and 6 grams of oxygen. Given that 16 grams of oxygen are produced, that corresponds to 16 grams of O₂, which comes from 6 grams of CO₂ and 6 grams of H₂O multiple times. Thus, when 22 grams of CO₂ and 9 grams of H₂O are used, we can find that glucose produced is 6.67 grams.
How much does 10 moles of water weigh?
As the molar mass of water is 18 g/mol (1*2 H + 16 O) 10 moles*18 g/mole=180 grams.
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 ounces is a gram o water?
1 oz = 28.34 grams 1 gram = 0.03 oz
What quantity of oxygen contains very nearly the same number of molecules as 36 grams of water?
To determine the quantity of oxygen that contains nearly the same number of molecules as 36 grams of water, we first calculate the number of molecules in 36 grams of water (H₂O). There are approximately 20 moles of water in 36 grams (since the molar mass of water is about 18 g/mol), which corresponds to about (1.2 \times 10^{24}) molecules. To find the equivalent amount of oxygen (O₂), we calculate that 20 moles of O₂ (with a molar mass of about 32 g/mol) would also contain (1.2 \times 10^{24}) molecules. Therefore, approximately 640 grams of oxygen (O₂) would contain a similar number of molecules as 36 grams of water.
How many moles of water are in an olympic swimming pool?
An Olympic swimming pool holds about 2,500 cubic meters of water, which is equivalent to 2,500,000 liters. Since one mole of water (H₂O) is approximately 18 grams and one liter of water has a mass of about 1,000 grams, this means there are roughly 2,500,000 moles of water in an Olympic swimming pool. Thus, you can estimate that there are around 138,888,889 moles of water in such a pool.
