What is the actual yield of carbon dioxide gas, if 2.0 g of sodium carbonate reacts with 5.0 g sulfuric acid, to form carbon dioxide gas with a 60.2% yield?

Respuesta :

Answer:

0.64 g.

Explanation:

Na2CO3  + H2SO4 --->  Na2SO4 + CO2 + H2O

82.99 g of Na2CO3 reacts with 98.07 g of H2SO4 to give 44 g of CO2

So 2 g of Na2CO3  gives a theoretical yield of  (44 / 82.99) * 2 = 1.06g CO2

If the yield is 60.2% the actual yield is 1.06 * 0.602

= 0.64 g.
