One look at a Periodic Table tells you the molar mass of sodium (Na) is 22.99 g/mol.

So multiply your mol value by the g/mol value to get a value in grams!

2.0x10-3 x 22.99 = !!!

For this you need the atomic (molecular) mass of N2. Take the number of moles and multiply it by the Atomic Mass. Divide by one mole for units to cancel. N2= 28.0 grams

2.23 moles N2 × (28.0 grams)= 62.44 grams N2

Nitrogen has 14.01 grams per mole. Therefore, 2 mole N has 2 * 14.01, or 28.02, grams.

67.2 grams.

One mole of N2 is equal to 28 grams (you get the atomic mass of Nitrogen, which is 14, and multiply it by two).

You then multiply 28 by 2.4 to get your answer.

1 mole N = 14.0067g N

2.00mol N x 14.0067g N/1mol N = 28.0g N

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 grams of NH3 can be produced from 4.46 mol of N2 and excess H2.?

The molecular weight of NH3 is 17.03-grams per mole and 14.01 for N2. The reaction is N2 + 3H2 = NH3. Therefore for every 1-mole of N2 as a reactant 1-mole of NH3 is produced. .2941-moles of NH3 is produced with a mass of 5.01-grams.


How many grams of NO are produced from the reaction of 2 mol of N2 with 2 mol of O2?

You have :N2 + O2 -----> 2NOmoles NO = ( 2 mols N2 reacted ) ( 2 mol NO / mol N2 reacted )moles NO = 4 moles NOmass NO = ( 4 mol NO ) ( 30 g NO / mol NO ) = 120 g NO


How many grams of NaN3 are required to produce 13.0 ft3 of nitrogen gas if the gas has a density of 1.25 gL?

13.0 cubic feet is equivalent to .3681 cubic meters, which is equivalent to 368.1 liters. At 1.25 grams/liter, there are 460.1 grams. Nitrogen gas has a molar mass of 28.0134 g/mol, so there are 16.4 moles of N2. The equation for the decomposition of NaN3 is 2 NaN3 --> 2 Na + 3 N2. So, for every 3 moles of N2, there must have been 2 moles of NaN3, hence there was 10.9 moles. With a molar mass of 65.01 g/mol, there were 709 grams of NaNO3 to begin with.


If you start with twenty eight grams of nitrogen and six grams of hydrogen what is the mass of ammonia formed?

Mr(N2) = ~28gmol-1, Mr(H2) = ~2gmol-1. This means there is 1 mole of N2 and 3 moles of H2; this will react completely, so there will be 28 + 6 = 34 grams of ammonia (NH3).
