At standard temperature and pressure, nitrogen exists as diatomic molecules. Therefore the number of atoms in 3.4 moles is 2 X 3.4 X Avogadro's Number, or 4.1 X 1024 atoms, to the justified number of significant digits.

What mass of nitrogen is needed to make 34 g of ammonia?
1 mole of nitrogen makes 3 of ammania so.. moles of ammonia=34/17=2 moles as 1 mole of nitrogen makes 3 of ammania so.. 2/3 x 2 x14 = 18.67 g
How many atoms are there in 34 grams of lithium?
Li atomic mass= 6.941g/mol= 4.9 moles of Li1.00 mol = 6.02 x 1023 atoms4.9 mol Li = 2.95 x 1024 atoms= 3.0 x 1024 atoms
How many mole of H atoms in 1 mole of H2O2?
17.32 moles H2O (2 moles H/1 mole H2O) = 34.64 moles hydrogen
How many Hydrogen atoms are in an Alkane with 16 Carbon atoms?
A non cyclic alkane always has a number of hydrogen atoms equal to 2c + 2, where c is the number of carbon atoms. Therefore, hexadecane, an alkane with 16 carbon atoms, will have 34 hydrogen atoms.

What mass of nitrogen is needed to make 34 grams of ammonia?
28 grams of Nitrogen is necessary to produce 34 grams of ammonia.
What is the number of moles in 54 grams of aluminum?
For this you need the atomic mass of Al. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.54.0 grams Al / (27.0 grams) = 2.00 moles Al
What is the Mass in Grams of 1.50 moles of hydrogen peroxide?
The molar mass of hydrogen peroxide is about 34; therefore, 1.5 moles has a mass of about 51 grams.
What is the composition of nitrogen and oxygen in boiled off air and water with the ordinary air?
nitrogen-65% and oxygen-30 to 34%
