How do you do the question: react 3.50 g of solid sodium metal with water to produce hydrogen gas and sodium hydroxide. If,at the end of the reaction there is 6.8 L of solution, what is the concentration of sodium hydroxide?

This is realy quite urgent. I need to know for my class's in 40 minutes.

  1. You're on a tight schedule. Most of the times we don't get the answers out that fast.
    2Na + 2H2O ==> 2NaOH + H2

    mols Na = grams/molar mass = ?
    M NaOH = mols NaOH/6.8 L = ?
