How much nitrogen is in nitrogen di oxide?
1 mol of nitrogen per 1 mol of oxygen. NO2
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 much energy is generate from freezing 2.5 g water?
2.5 g 1 mol/18.02 g (-285.83) kJ/mol
When you have 0.43 mol of NH4Cl how many total moles of ions are released when each of the following samples dissolves completely in water Show work so I can understand how to do it on my own?
When NH4Cl dissolves in water, it dissociates into NH4+ and Cl- ions. Since NH4Cl produces one NH4+ ion and one Cl- ion, for 0.43 mol of NH4Cl, there will be a total of 0.43 mol of NH4+ ions and 0.43 mol of Cl- ions released. Total moles of ions = 0.43 mol NH4+ + 0.43 mol Cl- = 0.86 mol ions The total moles of ions released when 0.43 mol of NH4Cl dissolves in water is 0.86 mol.
What is the molar mass of OH?
The molar mass of the hydroxide ion (OH-) is approximately 17 g/mol. This includes the combined mass of one oxygen atom (16 g/mol) and one hydrogen atom (1 g/mol) that make up the hydroxide ion.
How many mol CaCO3 can be dissolved in 0.0720 mol HCl?
The amount of substance that will dissolve depends on the temperature and the solvent used. Thus, there is no way to tell how much will dissolve unless such a test is actually carried out (since that concentration of acid is not a standard solvent used in such experiments).
How much octane can react with 0.740 of oxygen?
1 mol of octane (C8H18) reacts with 25 mol of oxygen (O2) to produce 8 mol of CO2 and 9 mol of H2O. Therefore, 0.74 mol of oxygen can react with 0.0744 mol of octane.
How many sulfur atoms are in 0.45 mol BaSO4?
There are 0.45 mol of BaSO4. In one mole of BaSO4, there is one sulfur atom. Therefore, there are 0.45 mol of sulfur atoms in 0.45 mol of BaSO4.
How much is a mol?
6.022 x 1023
How much hydrogen would be required to produce 7.5 mol of water?
To produce 1 mol of water, 2 mol of hydrogen is needed. Therefore, to produce 7.5 mol of water, you would need 15 mol of hydrogen.
How much nitrogen is in nitrogen di oxide?
1 mol of nitrogen per 1 mol of oxygen. NO2
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 much energy does sugar supply?
-5.63mJ/mol
How much energy is in 1 mol of an x-ray photon with a wavelength of .180 nm?
6.65X10^5 kj/mol
How many mol of AgCl can be precipitated by adding a solution containing 0.100 mol of AgNO3 to a solution containg excess NaCl?
One mole of AgNO3 reacts with one mole of NaCl to form one mole of AgCl precipitate. Therefore, 0.100 mol of AgNO3 will form 0.100 mol of AgCl precipitate when reacted with excess NaCl.
How many significant figures are in 0.0001 mol?
There are four significant figures in 0.0001 mol.
1 mol off sulfur atoms has how much mass?
The molar mass of sulfur is approximately 32.06 grams/mol. Therefore, 1 mol of sulfur atoms will have a mass of 32.06 grams.
