To find the molecular mass of a compound, add up all the masses of the individual atoms. In ammonia (NH3), we have one nitrogen (14.0 Atomic Mass units), and three hydrogens (1.01 amu each, or 3.03 amu total), so we get a total of 17.0 amu. The conversion for amu's to grams is: 1 amu = 1.66 x 10-24grams, so we find the mass for our ammonia molecule by multiplying 17.0amu x (1.66 x 10-24g/amu) = 2.82 x 10-23g.

100 grams of ammonia equals how many moles?
For this you need the atomic (molecular) mass of NH3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. NH3=16.0 grams100 grams NH3 / (16.0 grams) = 6.25 moles NH3
Calculate mass in grams of 2.110 moles of NH3?
You can find the mass of one mole of each of the individual elements by looking at the mass numbers.So, 1 mole of:N=14gH=1gsince there are 3 H's the total mass of 1 mole NH3 is 14+3=17gYou then multiply the actual number of moles by the g's per mole:=> 17x2.11=35.87g
How many nitrogen atoms are in the molecule NH3?
There is one nitrogen atom in the molecule NH3.
How many moles of NH3 can be produced from 14 grams of N2?
The molecular mass of NH3 is the sum of the atomic mass of nitrogen and three times the atomic mass of hydrogen, or 14.007 + 3(1.008) = 17.031. Therefore, the number of moles of NH3 in 14.0 grams is 14.007/17.031 = 0.822. Since each molecule of N2 supplies two nitrogen atoms and each molecule of NH3 needs only one nitrogen atom, the number of moles of N2 needed is half the number of moles of NH3 formed = 0.411.
How many moles of electrons are present in 17 grams of ammonia?
To find the number of moles of electrons in ammonia (NH3), we first need to calculate the number of moles of ammonia using its molar mass. The molar mass of NH3 is 17 g/mol. Therefore, 17 grams of NH3 is equal to 1 mole. Since there are 3 electrons in each molecule of ammonia, there are 6.022 x 10^23 electrons present in 1 mole of NH3.
What is the molar mass of a molecule?
The mass of one mole of substance, usually in grams or kilograms
What is the mass in gram of one molecule of caffeine (C8H10N402)?
To calculate the mass of one molecule of caffeine (C8H10N402), you need to add up the atomic masses of all the atoms it contains. The molar mass of caffeine is approximately 194.19 grams per mole. One molecule of caffeine will have a mass of 194.19 grams.
