Water its 11.2 percent by mass hydrogen How many kilograms of water would contain 5.0 grams of hydrogen?
To find the mass of water containing 5.0 grams of hydrogen, we need to set up a proportion using the mass percentage of hydrogen in water. Since water is 11.2% hydrogen by mass, we can calculate the mass of water using the formula: (5.0 grams of hydrogen) / (11.2 grams of hydrogen per 100 grams of water) = x grams of water. Converting grams to kilograms, the mass of water containing 5.0 grams of hydrogen would be 5.0 g / 11.2% = 44.64 g. This figure converted to kilograms is 0.04464 kg.
How many grams of water are formed in a reaction between hydrogen and 25 grams of oxygen?
25
How many atoms of hydrogen are in 5 grams of water?
6.6x1022 per gram of water
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 water are produced when 300 grams of hydrogen react with an unlimited amount of oxygen?
The atomic mass of hydrogen is 1.008 and the molecular mass of water, with formula H2O, is 18.015. Therefore, the mass of hydrogen to that of water has the ratio of 2(1.008)/18.015 = about 0.1119, and the answer to the problem is 300/0.1119 = 2.68 X 103 grams, to the justified number of significant digits.
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 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 grams of hydrogen are there in 207 grams of water?
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
How many grams of water are in one fl oz?
found the answer....there are 28.35 grams in one fl oz of water
How many grams of nitrogen in one gallon of pure water?
None. Pure water has only hydrogen and oxygen.
How many moles of hydrogen will it take to make 36 grams of water?
To make 36 grams of water (H2O), you would need 2 moles of hydrogen. This is because the molecular formula of water is H2O, meaning each molecule of water contains 2 atoms of hydrogen.
How many hydrogen atoms are present in 3.65 grams of water?
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
