Explanation / Answer

A) N2 + H2 ---> NH3

balence the reaction N2 +3H2 --> 2NH3

one mole of N2 react with 3 mole of H2 produce 2 mole of NH3

moles of N2 = (10.2 g/28.0 g) = 0.364 moles

moles of H2 = (1.22g/2.0g) = 0.61 moles

reacting ratio is 1:3:2 (N2:H2:NH3)

0.61 moles of H2 react with 0.2033 moles of N2 to produce 0.305 moles of NH3

mass of NH3 theoritical yeild = (0.305 moles x 17.031 g/mol ) = 5.1944 g

B) percentage yeild = actual yeild / theoritical yeild

moles of NH3 actual yeild = (1.48g / 17.031g/mol) = 0.0869 moles

percentage yeild =  (0.0869 moles / 0.305 moles) x 100 = 28.49 %

2) B 29.33g C6H12O6 in 1.33 L solution

molarity of solution = (moles of solute / volume of solution )

moles of C6H12O6 = (29.33g /180.1559 g/mol) = 0.1628 moles

molarity of solution (M) =  0.1628 moles / 1.33 L = 0.1224 M

c) moles of NaCl = (38.3mg / 58.44 g/mol) = 0.65537 m mol

molarity of solution (M) = 0.65537 m mol / 123.0ml = 0.005328 M

3) H2O molecules
