in the reaction between sodium and water, hydrogen gas is given off and sodium hydroxide is formed. The gas is collected and there is found to be 1.8 moles of hydrogen.
a) what mass of sodium would have been used in the reaction?
Balance the equation:
Na + 2HOH= NaOH + H2
so the mole ratio of Na:H2 is 1:1
how many grams of Na is in 1.8 moles>
