25 grams / (17 grams/mole) x 6.022x1023 molecules/mole = 8.9x1023 molecules
In ammonia (NH3), there are three hydrogen atoms for every molecule. The molar mass of ammonia is 17 grams per mole. To find the mass of hydrogen in 150 grams of ammonia, you can calculate as follows: 150 g x (3 g H2 / 17 g NH3) = 26.47 g of hydrogen.
Depends on the atomic mass of the molecule, the pressure, and the temperature
Since the molar mass of ammonia (NH3) is 17 g/mol and it contains 3 hydrogen atoms per molecule, the molar mass of hydrogen in ammonia is 3 g/mol. Therefore, in 150g of ammonia, there are (3/17) * 150 = 26.47g of hydrogen.

Ah, what a lovely question! To find the number of molecules in 1 gram of NH3, we first need to know its molar mass, which is approximately 17 grams per mole. Then, we use Avogadro's number, which tells us there are about 6.022 x 10^23 molecules in one mole of a substance. By dividing 1 gram by the molar mass of NH3 and then multiplying by Avogadro's number, we find there are roughly 3.55 x 10^22 molecules in 1 gram of NH3.
To find the mass in grams of 1.20x10^25 molecules of ammonia (NH3), you first calculate the molar mass of NH3 (17.031 g/mol). Then, divide the given number of molecules by Avogadro's number (6.022x10^23 molecules/mol) to find the number of moles, and finally, multiply the number of moles by the molar mass to get the mass in grams, which will be approximately 4.08x10^2 grams.
