NASA says 170,300 g of Oxygen (O2) per person is needed for a 6-month mission. Space X, a private company that partners with NASA claims the law does not apply in space and that only 127,500 grams of water are needed.

How many grams of water (H2O) is needed to meet the Oxygen demands? Use Stoichiometry to determine your answer.

The mass of water (H₂O) needed to meet the oxygen demand is 191587.5 g

Balanced equation

2H₂ + O₂ —> 2H₂O

Molar mass of O₂ = 16 × 2 = 32 g/mol

Mass of  O₂ from the balanced equation = 1 × 32 = 32 g

Molar mass of H₂O = (2×1) + 16 = 18 g/mol

Mass of H₂O from the balanced equation = 2 × 18 = 36 g

SUMMARY

From the balanced equation above,

32 g of O₂ reacted to produce 36 g of H₂O

How to determine the mass of water

From the balanced equation above,

32 g of O₂ reacted to produce 36 g of H₂O

170300 g of O₂ will react to produce = (170300 × 36) / 32 = 191587.5 g of H₂O

Thus, 191587.5 g of H₂O is needed to meet the oxygen demand
