Question

A 13.00 g sample of citric acid reacts with an excess of baking soda as shown in the equation. mc011-1.jpg What is the theoretical yield of carbon dioxide? 0.993 g 2.98 g 3.65 g 8.93 g

Answer 1

Hii buddy,

When citric acid reacts with abundance of baking soda, following reaction occurs.

C6H8O7 + 3× NaHCO3 → Na3C6H5O7 + 3H2O + 3CO2

1 mole of citric acid → 3 moles of carbon dioxide

For citric acid

W1 = 13g

M1 = 6×1+8×1+16×7 = 192g

n1 = W1/M1 = 13/192 moles

For carbon dioxide

n2 = 3× 13/192 = 13/64 moles

M2 = 12×1+16×2 = 44g

W2 = n1×M1 = 44× 13/64 = 143/16 = 8.937 g

Thus theoretical yield of CO2 is 8.94 g.

Hope that helps...
