Answer: V = 16.1 L

Explanation:Using Ideal gas law formula PV = nRT, we will derive for Volume. V = nRT / P

V = 0.34 mole ( 0.0820574 L.atm/ mole .K)(321 K ) / 0.5567 atm

= 16.1 L

A 13.00 g sample of citric acid reacts with an excess of baking soda as shown in the equation. What is the theoretical yield of

julia-pushkina [17]

Chemical equation of the reaction between citric acid and baking soda:

$C_{6} H_{8} O_{7} +3NaHCO_{3} -\ \textgreater \ Na_{3} C_{6} H_{5} O_{7} +3 H_{2} O+3CO_{2}$

Ratios

Citric Acid Baking soda -> Sodium Citrate Water Carbon Dioxide
C6H8O7 CO2
1 mole 3moles

Molecular masses
Citric acid
6*12 + 8*1 + 7*16 = 192 g/mole
Carbon dioxide
12 + 2*16 = 44 g/mole

Proportion carbon dioxide / citric acid

3 * 44 g of carbon dioxide / 192 g of citric acid

132 g of carbon dioxide / 192 g of citric acid

13.00 g of citric acid * [132 g of carbon dioxide / 192 g of citric acid] = 8.94 g of carbon dioxide.

Answer: 8.94 grams.
