What volume of H2 gas (in liters), measured at 27 °C and 737 torr, can be obtained by reacting 4.95 g of zinc metal with 121 mL of 0.305 M HCl? The equation is______ L H2(g) A 0.228 g sample of impure NaOH requires 17.1 mL of 0.2370 M HCl for neutralization. What is the percent of NaOH in the sample, by weight?_____% NaOH In an acid-base titration, 20.54 mL of H2SO4 were used to neutralize 33.96 mL of 0.322 M NaOH. What was the molarity of the H2SO4 solution?_____ M H2SO4 A 10.6 mL sample of HNO3 was diluted to a volume of 108.19 mL. Then, 21 mL of that diluted solution were needed to neutralize 48.5 mL of 0.41 M KOH. What was the concentration of the original nitric acid?________M HNO3 (original solution) If 380 mL of 0.35 M Ba(OH)2 are added to 500. mL of 0.65 M HCl, will the mixture be acidic or basic? Find the pH of the resulting solution. The solution will be: basic or acidic pH______=
