Question

The equation for the reaction of sodium with water is as follows:
2Na(s) 2H2O(l) £ H2(g) 2NaOH(aq)
How many liters of H2 are produced when 12.0 g of Na reacts with H2O at
293 K and 99.3 kPa?

DrBob222 · Answer

Convert 12.0 g Na to moles. moles = grams/molar mass.

Using the coefficients in the balanced equation, convert moles Na to moles H2.

Use PV = nRT with p in atm, n is moles, and T in Kelvin to determine volume in L.
