How many milliliters of 0.250 M Sulfuric acid are required to react with 8.20 g of Sodium Hydrogen Carbonate (Na=23.0, H=1.0 amu, C=13.0
amu, O=16.0 amu, S =32.0 amu)
H2SO4 + 2 NaHCO3 → Na2SO4 +2 H2O + CO2

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
