A KHP solution was made by adding approximately 30 mL of deionized (DI) water to your KHP beaker. The KHP solution was then titrated, and 28.32 mL of a NaOH solution was required to reach the endpoint of the titration. 1.3561 g of an unknown solid was transferred to a clean, dry Erlenmeyer flask, and approximately 20 mL of DI water was added. The unknown solution was titrated, and 17.88 mL of the same NaOH solution was required to reach the endpoint of the titration. What was the %KHP by mass in the unknown sample solid

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
