1) What volume of 0.250 M sulfuric acid (in milliliters) is needed to react completely with 2.17 g of potassium bicarbon

[answerhappygod]

1) What volume of 0.250 M sulfuric acid (in milliliters) is
needed to react completely with 2.17 g of potassium
bicarbonate?
Use these atomic masses: potassium = 39.098 amu ; hydrogen =
1.008 amu; carbon = 12.011 amu; oxygen = 15.999 amu.
2) If 20.0 mL of 0.25 M cobalt(III) sulfate solution is combined
with 20.5 mL of 0.375 M sodium hydroxide solution, what is the
maximum mass (in grams) of precipitate that can form?
Atomic masses: Cobalt = 58.933 amu; Sulfur = 32.066 amu; Oxygen
= 15.999 amu; Sodium = 22.990 amu; Hydrogen = 1.008 amu
