Calculate the pH of a solution formed by mixing 500.0 mL of 0.15 M HCHO2 with 200.0 mL of 0.20 M LiCHO2. The Ka for HCHO2 is 1.8 × 10-4.

Find the critical value zα/2 that corresponds to a degree of confidence of 64%.

Use the given degree of confidence and sample data to construct a confidence interval for the population proportion p. Don’t forget your sentence. Round all values to nearest hundredths place. (Don’t forget to state the critical value, margin of error, confidence interval AND statement.)n = 192, x = 64; 90 percent confidence
