Answer to Question #260013 in General Chemistry for jashuhg

Question

A sample of oxygen gas, which is saturated with water vapour,is kept in a10- L vessel at 30° C and has a pressure of 758 Torr. If the pressure of the water

vapour at this temperature is 31.8Torr, what would be the pressure of the dry

oxygen?

a. Balance the chemical equation;

b. Identify the limiting reactant and the excess reactant if applicable;

c. Compute for the theoretical yield;

d. Determine the percent yield of the reaction;

e. Calculate the percent error and

f. Compute for the excess amount of the excess reactant if applicable.

Answer 1

Explanation:

P(O2) = P(O2 + H2O) - P(H2O)

P(O2) = 758.0 to rr - 31.8 to rr

P(O2) = 726.2 to rr
