2.035 gH ow to use stoichiometry to convert es of reactants and products in chemical Submit My Answers Give Up Correct escribes the quantitative relationships tants and products of a balanced reaction aring mole ratios. Stoichiometry can be mass, number of moles, or number of an nrnducts and reactants as shown in Part D How many molecules (not moles) of NH are produced from 2.32 10 g of H2? Express your answer numerically as the number of molecules. of 1 number of Hints molar mass moles from balanced molecules equation moles Submit Avogadro's number molar mas My Answers Give Up of Incorrect; Try Again; 3 attempts remaining mass Continue 18

Explanation / Answer

N2 +    3 H2    -------------> 2 NH3

mass of H2 = 2.32 x 10^-4 g

moles of H2 = 2.32 x 10^-4 / 2 = 1.16 x 10^-4 mol

from the equation :

3 mol H2   ---------------> 2 mol NH3

1.16 x 10^-4 mol H2 ----------------> ??

moles of NH3 produced = 1.16 x 10^-4 x 2 / 3

                                      = 7.73 x 10^-5

1 mol NH3   ----------------> 6.023 x 10^23 molecules

7.73 x 10^-5 mol   -------------> ??

number of moleucles of NH3 = 7.73 x 10^-5 x 6.023 x 10^23

                                           = 4.66 x 10^19 molecules
