Question

Based on both the experimental results and the current price of sulfuric acid and hydrochloric acid, which acid is better for hydrogen gas production? Assume the following recent prices for these acids: 500. mL of 9.0 mol/L sulfuric acid solution = $14.95 and 100. mL of 12.0 mol/L hydrochloric acid = $7.50.

Answer 1

50 mL for one sample
and
46.5mL for another sample

Answer 5

I actually have 4 samples of H2 gas trials 1 and 3 use 0.70M of HC and trials 2 and 4 use 0.50M of HC.

Answer 6

But I took the average of 1 and 3 as well as 2 and 4
