Question

the synthesis of products is limited by the amount of reactants added to the reaction flask. if one mole each of ch₄, nh₃, h₂s, and co₂ is added to 1 liter of water in a flask (1 liter of water = 55.5 moles of h₂o), how many moles of hydrogen, carbon, oxygen, nitrogen, and sulfur are in the flask? round your answers to the nearest whole number. how many moles of hydrogen? mole(s) how many moles of carbon? mole(s) how many moles of oxygen? mole(s) how many moles of nitrogen? mole(s) how many moles of sulfur? mole(s)

Explanation:

Step1: Analyze hydrogen moles

For $CH_4$: 1 mole of $CH_4$ has 4 moles of H; for $NH_3$: 1 mole of $NH_3$ has 3 moles of H; for $H_2S$: 1 mole of $H_2S$ has 2 moles of H; for $H_2O$: 55.5 moles of $H_2O$ has $55.5\times2$ moles of H. Total moles of H = $4 + 3+2+55.5\times2=4 + 3+2 + 111=120$.

Step2: Analyze carbon moles

Only $CH_4$ and $CO_2$ have carbon. 1 mole of $CH_4$ has 1 mole of C and 1 mole of $CO_2$ has 1 mole of C. Total moles of C = $1 + 1=2$.

Step3: Analyze oxygen moles

Only $CO_2$ and $H_2O$ have oxygen. 1 mole of $CO_2$ has 2 moles of O and 55.5 moles of $H_2O$ has 55.5 moles of O. Total moles of O = $2+55.5 = 57.5\approx58$.

Step4: Analyze nitrogen moles

Only $NH_3$ has nitrogen. 1 mole of $NH_3$ has 1 mole of N. So moles of N = 1.

Step5: Analyze sulfur moles

Only $H_2S$ has sulfur. 1 mole of $H_2S$ has 1 mole of S. So moles of S = 1.

Answer:

How many moles of hydrogen? 120 mole(s)
How many moles of carbon? 2 mole(s)
How many moles of oxygen? 58 mole(s)
How many moles of nitrogen? 1 mole(s)
How many moles of sulfur? 1 mole(s)
