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.
1 g of NH3 is approximately equal to 17.03 moles. One mole of NH3 contains 6.022 x 10^23 molecules, so 1 g of NH3 would contain approximately 1.024 x 10^23 molecules.
25 grams / (17 grams/mole) x 6.022x1023 molecules/mole = 8.9x1023 molecules
Answer: 4.3 gram
Each mole of NH3 is 14 g + 3 times 1 g = 17 g in total,
so:
0.25 mole = 0.25 x 17 = 4.3 gram
1g of NH3 is 0.5871645822324moles (divide by 17.031). Now multiply this by avagadros number of 6.022x10^23, and you get 3.536x10^23 molecules.
NH3 = 17g/mol, and 25/17 = about 1.5mol. 1.5 x (6x10^23) = 9x10^23, which represents the number of NH3 molecules. NH3 = 4 atoms per molecule, so (9x10^23) x 4 = 3.6x10^24 atoms total.
25 grams of nitrogen trihydride (NH3) is equivalent to 1,468 moles.

How many molecules -not moles- of NH3 are produced from 3.07104 g of H2?
To find the number of NH3 molecules produced, we would first need to determine how many moles of H2 are in 3.07104 g. Then, we would use the stoichiometry of the balanced chemical equation to find the number of NH3 molecules produced from that number of moles of H2.
How many molecules are in 75g of N2O3?
To find the number of molecules in 75g of N2O3, you first need to calculate the number of moles using the molecular weight of N2O3 (76.01 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules.
What is the mass of 1.75 1024 molecules of NH3?
To find the mass of 1.75 x 10^24 molecules of NH3, you would first calculate the molar mass of NH3 (17.03 g/mol). Then, you would convert the number of molecules to moles by dividing by Avogadro's number (6.022 x 10^23 molecules/mol). Finally, multiply the number of moles by the molar mass to find the mass.
How many molecules (not moles) of NH3 are produced from 5.69104 g of H2?
First, calculate the number of moles of H2 using its molar mass of 2 g/mol. Then, use the balanced chemical equation for the reaction between H2 and NH3 to determine the mole ratio. Finally, convert the moles of H2 to moles of NH3 using the mole ratio and then calculate the number of molecules of NH3 produced.
Results for Calculate The Amount In Moles Of Molecules For Each Substance. A) A Sample Of Ammonia NH3(g) Containing 8.1x1020 Atoms Of Hydrogen?
To calculate the amount in moles of NH3 molecules, first determine the number of moles of hydrogen atoms. Given that there are 8.1x10^20 atoms of hydrogen, divide this by Avogadro's number (6.022x10^23) to find the amount in moles. Since there are 3 hydrogen atoms in each ammonia molecule, the amount of NH3 molecules would be one-third of the amount of hydrogen atoms in moles.
