Question

In the equation 2Na + H2SO4 = Na2SO4 + H2, ______ g of sodium reacts with _______ g of sulphuric acid to form ______ g of sodium sulphate and ______ g of hydrogen gas. (At. wt. Na=23, S=32, O=16, H=1)​

Answer 1

Answer:

Sodium Sulfate's Atomic Mass is 142.1 grams/mol. Sodium Hydroxide's Atomic Mass is 40 grams/mol. The ratio of NaOH to Na2SO4 is 2:1 so we divide the resulting 5 moles of NaOh by 2. 2.5 moles x 142.1 grams/mol (NaSO4)=355.25 or 355.2 grams of Sodium sulfate are produced.07-Nov-2014
