Solve the below problem.
blagie [28]

the balanced equation for the formation of ammonia is as follows

N₂ + 3H₂ --> 2NH₃

stoichiometry of H₂ to NH₃ is 3:2

in gases number of moles of gas is directly proportional to volume of gases.

therefore molar ratio is equal to volume ratios.

this means volume ratio of H₂ to NH₃ is 3:2

volume of H₂ reacted - 54.1 L

if 3 L of H₂ forms - 2 L of NH₃

then 54.1 L of H₂ forms - 2/3 x 54.1 = 36.1 L of NH₃

volume of NH₃ formed is 36.1 L

How many moles are there in 8.50 X 1024 molecules of sodium sulfate, Na2SO3?
DiKsa [7]
Hello!

To solve this question, we need to use the Avogadro's Number, which is a constant first discovered by Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are 6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:

8,50* 10^{24}molecules* \frac{1 mol Na_2SO_3}{6,02* 10^{23}molecules}=14,12 molesNa_2SO_3

So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent 14,12 moles of Na₂SO₃ 

Have a nice day!

How many moles of nitrogen, N, are in 61.0 g of nitrous oxide, N2O?
Oksana_A [137]

Answer:

2.77 mol N

Explanation:

M(N2O) = 2*14 + 16 = 44 g/mol

61.0 g * 1 mol/44g = (61/44) mol N2O

                       N2O ---- 2N

                    1 mol         2 mol

            (61/44) mol        x mol

x = (61/44)*2/1 = 2.77 mol N

Calculate the density of a sample of gold if the sample has a volume of 48.9cm3 and a mass of 944.75 g
LekaFEV [45]

Answer:

19.3g/cm^3

Explanation:

Hey,

the formula for density is Mass/Volume so in this question you basically put the given things in the formula

D = M/V

D= 944.75/48.9

D= 19.3g/cm^3
