No, this would make 5 moles. This is because water is H2O. This means that for each oxygen molecule used, there will be 2 hydrogen molecules used. In the given equation Only 5 moles of oxygen could be used to pair with all 10 moles of hydrogen, therefore giving you an excess of 5 oxygen molecules.
3 moles of O, so that must be 6 moles of O2
We need 8 moles potassium chloride.
To calculate the number of molecules, first convert 450 g of water to moles (8 moles). With a 1.3 m solution, there are 1.3 moles of sucrose for every 1 liter of water. So, you will need 10.4 moles of sucrose for 8 moles of water. Finally, use Avogadro's number to convert moles to molecules, giving you approximately 6.23 x 10^23 molecules of sucrose.
Hydrochloric acid is a mixture water: acid with different concentrations.For hydrogen chloride (HCl) you need 0,475 moles.
To make a two mole salt solution in two liters of water, you'll need 4 moles of salt (2 moles/L * 2 L = 4 moles). The molar mass of salt (NaCl) is approximately 58.44 g/mol, so 4 moles would be 233.76 grams (4 moles * 58.44 g/mol = 233.76 g).
Write out the equation first: 10H2 + 10O2 --> xH2O Since there are 2 moles of Hydrogen for every mole of Oxygen and equal moles of both are given, the Hydrogen limits the reaction as the limiting reactant. 10 moles of Hydrogen can make 10 moles of H2O with 5 moles of Oxygen left over. Think of it logically: H2 is two hydrogen atoms and water needs two hydrogen atoms, so it is a one-to-one reaction.
3.2 moles of water (H2O)
3 moles of O, so that must be 6 moles of O2
4 moles of oxygen atoms are present in 4 moles of H2O
To find the total moles of KNO3 needed, use the formula: moles = molarity x volume (in liters). So, moles = 2.0 mol/L x 1.5 L = 3.0 moles of KNO3. Therefore, 3.0 moles of KNO3 need to be dissolved in water to make 1.5 liters of a 2.0 M solution.
To make a 2 M solution of KCl in 4 L of water, you would need 8 moles of KCl. This is because Molarity (M) is defined as moles of solute divided by liters of solution. In this case, 2 M means 2 moles of KCl per liter, which totals 8 moles for 4 liters.

for each mole of anything there is 6.022x10^23 molecules. Therefore for 5 moles of water there is 5 x 6.022x10^23 = 3.011x10^24 molecules 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.
Hydrochloric acid is a mixture water: acid with different concentrations.For hydrogen chloride (HCl) you need 0,475 moles.
By dissolving 2 moles of the compound in 1 L of water
