How many total atoms are in the compound CHNO?
Cyanic acid contain four atoms.
How many moles of sulfuric acid are present in 0.550 L of a 0.150 M sulfuric acid solution?
.150 M is the molarity of the solution, which is the number of moles per liter. So all you need to do is multiply the molarity by the number of liters. So .150 moles/liter x .550 L = .0825 moles
How many moles of chlorine are in 3.4 moles of hydrolic acid?
In hydrochloric acid (HCl), there is one mole of chlorine for every mole of hydrochloric acid. Therefore, in 3.4 moles of hydrochloric acid, there are also 3.4 moles of chlorine.
How many moles of H ions are present in the following aqueous solution 1410 mL of 0.32 M nitric acid?
To find the number of moles of H ions in the solution, first calculate the moles of HNO3 using the given concentration and volume. Since each mole of HNO3 yields 1 mole of H ions in solution, the number of moles of H ions is the same as the moles of HNO3. Therefore, in this case, there are 0.4512 moles of H ions present in the solution.
How many moles of H2O are present in 150.0G of H2O?
The answer is 8,33 moles.
How many moles of Mg are present in 14.95 g?
The answer is 0,615 moles.
How many moles of carbon hydrogen and oxygen are present in a 100-g sample of ascorbic acid?
Ascorbic acid (vitamin C) has the chemical formula C6H8O6. In a 100-g sample, you can calculate the number of moles of each element by first determining the molar mass of ascorbic acid, which is approximately 176.12 g/mol. Using this, you can find that there are about 0.568 moles of ascorbic acid in the sample. Consequently, this corresponds to 3.41 moles of carbon (C), 4.54 moles of hydrogen (H), and 0.68 moles of oxygen (O) based on the stoichiometric ratios in the formula.
A flask contains 300.0cm3 of a 0.500 acid solution How many moles of the pure acid must have dissolved?
All of the moles of pure acid will have dissolved in the flask.
How many moles of HCI are present in 35.0 mL of a 4.5 M solution of nitric acid?
To find the number of moles of HCl, first calculate the number of moles of nitric acid present in the solution using the formula n = M x V, where M is the molarity and V is the volume in liters. Then, since nitric acid is HNO3 and not HCl, you'll need to ensure you're performing the calculations with the correct compound.
How many moles of H2O are present in 75.0g H2O?
There are 4.17 moles of H2O present in 75.0g of H2O.
How many moles of H are in 0.75 moles of H2SO4?
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
How many moles of oxygen are present in a flask with 1.5 L?
The answer is 14,93 moles.
