You must use 64.43 g H₂O.

Balanced chemical equation: H₂O + CO₂ → H₂CO₃

Moles of CO₂ = 157.35 g CO₂ × (1 mol CO₂/44.01 g CO₂) = 3.5753 mol CO₂

Moles of H₂O = 3.5753 mol CO₂ × (1 mol H₂O/1 mol CO₂) = 3.5753 mol Fe

Mass of H₂O = 3.5753 mol H₂O × (18.02 g H₂O /1 mol H₂O) = 64.43 g H₂O

Answer:

57.8kg

Explanation:

Potential energy is given by:

$U =mgh$

Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:

$3400=m(9.8)(6)\\3400=58.8m\\m=57.8kg$
