There are 10 electrons per molecule of NH3,17g of ammonia means one mole, therefore 10 moles of electrons are present.
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
0,522 moles of ammonia contain 3,143.10e23 molecules of NH3.
Molar mass of ammonia is 17 g. Therefore in 12 x 10.3 g of ammonia there will be 7.27 moles of ammonia.
If ammonia (NH3) has a molar weight of 17 grams per mole, then 10 moles means 17x10=170 grams.

The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
3 moles of ammonia is 51grams. One mole is 17 grams.
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
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
0,522 moles of ammonia contain 3,143.10e23 molecules of NH3.
Molar mass of ammonia is 17 g. Therefore in 12 x 10.3 g of ammonia there will be 7.27 moles of ammonia.
If ammonia (NH3) has a molar weight of 17 grams per mole, then 10 moles means 17x10=170 grams.

How many MOLES of sodium nitrate are present in 2.85 grams of this compound ?
That amount of ammonia contains two moles of hydrogen gas. One mole of hydrogen gas weighs 2.016 grams. Therfore 3.75 grams of ammonia contains two moles of hydrogen.
Ammonia is NH3 (not NH2) so its molar mass is 17 g/mol. In 1.2*10^3 g there are1.2*10^3(g) / 17 (g/mol) = (70.6 =) 71 mol NH3.
