Hydrogen gas can be prepared by reacting metallic sodium with water: 2na(s) + 2h2o(l) → h2(g) + 2naoh(aq). if the price of sodium were 165/kg, what would be the cost of producing 1.00 mol of hydrogen. ignore the cost of the water.

$7.59

Explanation:

From the balanced reaction equation, 2moles of sodium is required to produce 1.0 mole of hydrogen.

Now, the mass of 2 moles of sodium is 23.0×2 = 46 of sodium.

The mass of sodium required in kilograms is 46/1000= 0.046Kg of sodium

If 1 Kg of sodium cost $165

0.046Kg of sodium will cost 0.046×165 = $7.59

Therefore it will cost $7.59 to produce 1.0 moles of hydrogen gas according to the equation.
