This is a chemical calculation. there are 0.04166 moles in it.
The number of ammonia molecules is 59 720.10e23.
The mass of ammonia is 339,7 g.
The number of ammonia molecules is 5,83.10e19.
Molar mass of ammonia is 17 g. Therefore in 12 x 10.3 g of ammonia there will be 7.27 moles of ammonia.
divide the mass by molar mass. Molar mass of NH3 is 17. answer is 0.044mol
The number of ammonia molecules is 59 720.10e23.
The mass of ammonia is 339,7 g.
The mass of 3 mol of ammonia is 51,093 g; the number of ammonia molecules in 3 moles is18,066422571.10e23.
This value is 21,85 g.
The mass of 5 mol of ammonia is 85,155 g; the number of ammonia molecules in 5 moles is3,011 070 428 5.10e24.
The number of ammonia molecules is 5,83.10e19.
Assuming that this ammonia gas is at STP, you can use Avogadro's number to gind the number of moles of gas:(387 x 1021 molecules) x (1 mol / 6.02x1023particles) x (17.03 g / 1 mol) =110 g NH3
Gram mole is the mass of a substance which equal to molecular mass in amu. For ammonia we have one nitrogen atom and three atoms of hydrogen. So the molecular mass in amu will be 14+3 = 17 Now 17 g of ammonia would have 6.023 x 1023 molecules. ie avagadro number of molecules. Hence every 1 g will have (6.023/17) x 1023 So for 32 g it would have (32/17) x 6.023 x 1023 molecules.

1 g of ammonia (NH3) is equal to 0,059 mol.
Molar mass of ammonia is 17 g. Therefore in 12 x 10.3 g of ammonia there will be 7.27 moles of ammonia.
divide the mass by molar mass. Molar mass of NH3 is 17. answer is 0.044mol
