Buret milliliters = (205 × 8.0) ÷ (800 × 0.4) = 5.13 mL
Multiply the 5.13 mL by 4 to adjust for the decrease in the sample size:
5.13 mL × 4 = 20.5 mL
If the buret method multiplies the number of milliliters of titrant by a factor to
calculate the concentration of the sample, multiply 20.5 by that factor.
Section 7 Troubleshooting
If the actual number of digits necessary is not within 1% of the expected number
of digits during an accuracy check, refer to Figure 6.
