According to the equation 2na + 2h2o mc012-1.jpg 2naoh+h2, what mass of na is required to yield 22.4 l of h2 at stp? (the atomic mass of na is 22.99 u.)

2Na+2H2O-->2NaOH+H2 at STP The standard temperature is 273 K (0° Celsius) and the standard pressure is 1 atm pressure. At STP, one mole of gas occupies 22.4 L of volume (molar volume). so number of moles of H2 is 1 look at the mole ratio of sodium to hydrogen its 2:1
