The number of mol of 6 percent hydrogen peroxide?
H2o2
What is the percent composition of each element found in ammonium sulfide?
The formula unit for ammonium sulfide is (NH3)2S. There are 2 nitrogen atoms, 6 hydrogen atoms, and 1 sulfur atom per formula unit. Its molar mass is 66.12g/mol. Mass of Nitrogen = 14.007g/mol x 2 = 28.014g/mol Percent Composition of Nitrogen = (28.014g/mol)/(66.12g/mol) x 100 = 42.37% Mass of Hydrogen = 1.008g/mol x 6 = 6.048g/mol Percent Composition of Hydrogen = (6.048g/mol)/(66.12g/mol) x 100 = 9.147% Mass of Sulfur = 32.06g/mol Percent Composition of Sulfur = (32.06g/mol)/(66.12g/mol) x 100 = 48.49% 42.37% + 9.147% + 48.49% = 100.00%
How many moles of hydrogen gas can be lberated from 104 mol of magnesium if the process operates at 75 percent efficiency?
Assuming you mean liberated, none. Magnesium does not contain hydrogen.
How many mol of H are in 4.51 mol H2O?
4,51 moles hydrogen exist.
What is the percent composition of hydrogen in water?
The formula for water is H2O: Molar mass = 18.02 g / mol H2OIn one mole of H2O there are 2 mol H and 1 mol O:2 mol H1.010 g H = 2.020 g H1 mol H1 mol O16.00 g O = 16.00 g O1 mol OThe percentage of each element is calculated from the quantities in 1 mole as:% element = g element 100g H2O% H...=...2.020 g H... 100......=...11.21 % H18.02g H2O% O...=...16.00 g O... 100......=...88.79 % O18.02g H2ONote: 11.21 + 88.79 = 100.00
How many hydrogen atoms are in 0.63 mol of (NH4)2SO4?
0.63 mol of (NH4)2SO4 contain 3,978.10e23 hydrogen atoms.
What is the empirical formula of a compound that contains 32.39 percent sodium 22.53 percent sulfur and 45.07 percent oxygen?
First assume you have 100 g of the substance & then convert to moles using the molecular weight of each element:Na: 32.39 g / (22.99 g/mol) = 1.409 mol NaS : 22.53 g / (32.07 g/mol) = 0.703 mol SO : 45.07 g / (16.00 g/mol) = 2.817 mol ONext divide each mole amount by the smallest one of the group, in this case sulfur. This gives you the ratio of each element in the compound.Na: 1.409 mol / 0.703 mol = 2.00S : 0.703 mol/0.703 mol = 1.00O: 2.817 mol/0.703 mol = 4.01Round to the nearest whole number & you get the formula: Na2SO4 (sodium sulfate)
How many moles of nitrogen are required to convert 9 mol hydrogen gas to ammonia gas?
9H2 + 3N2 ------> 6NH3 3 moles of N2 would be required.
Is hydrogen another name for water?
No. Hydrogen is H (14 g/mol) and Water is H2O (14x2+16 so 44 g/mol).
How do you Convert 86.2 grams c small 2 hsmal 4 to moles?
Carbon (C) has a atomic weight of 12 gr/mol Hydrogen (H) has an atomic weight of 1 gr/mol Therefore C2H4 has a molecular weight of 28 gr/mol (2x12 + 4x1) By dividing 86.2 grams by 28 gr/mol, you get 3.59 moles.
How much hydrogen would be required to produce 7.4 mol of water?
7.4 mol of H2
Cyclopentane has the molecular formula C5H10 How many moles of hydrogen atoms are there in 4 moles of cyclopentane?
The conversion. 4 mol C5H10 ( 10 mol H/1 mol C5H10 ) = 40 mol Hydrogen.
