Hello! Can somebody help to figure out this pls? Sodium reacts in water to form sodium hydroxide and hydrogen gas. Write a balanced equation for this reaction and calculate how many grams of it are needed to prepare 8 g of sodium hydroxide by this method. Ar(H)=1 Ar(O)=16 Ar(Na)=23 Balanced equation: 2 Na + 2 H2O --- 2 NaOH + H2 Sodium hydroxide mass: 40 g I could easily figure out the balanced equation, but I dont know how to do the rest. Thx!
