divide the mass by molar mass. Molar mass of NH3 is 17. answer is 0.044mol
To find the number of moles in 12 x 10.3 grams of ammonia (NH3), you first need to calculate the molar mass of NH3 (17.03 g/mol). Then divide the given mass (12 x 10.3 g) by the molar mass to get the number of moles, which should be approximately 72 moles.
To find the number of moles of hydrogen in 6.50 g of ammonia (NH3), first calculate the molar mass of ammonia (17.03 g/mol). Since ammonia has 3 hydrogen atoms, each with a molar mass of 1.01 g/mol, one mole of ammonia contains 3 moles of hydrogen atoms. Therefore, 6.50 g of ammonia contains (6.50 g / 17.03 g/mol) * 3 moles of hydrogen atoms.
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
To find the number of molecules in 0.75 g of ammonia, we need to first calculate the number of moles using the molar mass of ammonia (17 g/mol). Then we can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. In this case, the number of molecules in 0.75 g of ammonia would be approximately 1.26 x 10^22 molecules.
If ammonia (NH3) has a molar weight of 17 grams per mole, then 10 moles means 17x10=170 grams.
There are approximately 0.023 moles of ammonia in 1 g of ammonia (NH3).
1 g of ammonia (NH3) is equal to 0,059 mol.
To find the number of moles in 12 x 10.3 grams of ammonia (NH3), you first need to calculate the molar mass of NH3 (17.03 g/mol). Then divide the given mass (12 x 10.3 g) by the molar mass to get the number of moles, which should be approximately 72 moles.

Therefore, 6.50 g of ammonia contains (6.50 g / 17.03 g/mol) * 3 moles of hydrogen atoms.
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
The mass of ammonia will be 95,03 g.
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
3,44 moles H2 react with 1,146 moles NH3. The limiting reactant is hydrogen. O,244 moles N2 remain. 19,5 g NH3 are obtained.

Ammonia = NH3Molecular mass = 16.0Formula of grams to moles: grams / molecular mass = moles170,000 g / (16.0) = 10,600 moles NH3Note that the answer is with three significant digits
To find the number of molecules in 0.75 g of ammonia, we need to first calculate the number of moles using the molar mass of ammonia (17 g/mol). Then we can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.

The balanced chemical equation for the reaction between ammonia (NH3) and oxygen (O2) is 4NH3 + 3O2 → 2N2 + 6H2O. From the equation, we can see that 3 moles of O2 are needed to react with 4 moles of NH3. This means the molar ratio of O2 to NH3 is 3:4. First, calculate the number of moles of NH3 in 200.0 g: 200.0 g NH3 / 17.03 g/mol NH3 = 11.75 moles NH3 Now, calculate the number of moles of O2 needed using the molar ratio: 11.75 moles NH3 * (3 moles O2 / 4 moles NH3) = 8.81 moles O2 Finally, convert moles of O2 to grams: 8.81 moles O2 * 32 g/mol O2 = 282.0 g O2.
