What is the quantity of hydrogen gas liberated when `46 g` sodium reacts with excess ethanol ?
(Given atomic mass of `Na = 23`)

Calculate the volume, mass and number of molecules of hydrogen liberated when 230 g of sodium reacts with excess of water at STP (atomic masses of Na = 23U, O = 16 U and H = 1U).

Calculate the volume, mass and number of molecules of hydrogen liberated when 230 g of sodium reacts with excess of water at STP. (atomic masses of Na = 23U, O = 16U, and H = 1U) the balanced equation for the above reaction is {:(2Na_((s))+2H_(2)O_((l)),,to2NaOH_((aq)) +H_(2(g))+H_(2(g))uparrow),((2xx23)U+ 2(2xx1 +1 xx 16)U,,to2(23+16+1)U+(2xx1)U),(46 U + 36U,,to80U + 2U),(or46g + 36g ,, to 80 g + 2 g):}
