Question

1. Does calibration using standards help to improve the accuracy or the precision of the experiment?

2. Fill in the blanks of this table with appropriate conversions

μl	mL	L
5000		5 * 10^-3
	60

3. Given the following values, calculate the density of water.

Buret segment mass (g)	18.825
Buret segment mass with sample (g)	24.174
Largest volume increment, Vb (mL)	50.00
Initial Volume Reading, Vi (mL)	44.35
Volume Reading with T probe (mL)	43.18

Answer 1

Solution:

1) Calibration using standards means to compare the known measurement with measurement of instrument. Thus, calibration using standards improves the accuracy of the of the experiment.

2) Conversions are:

5000 uL = 5000 x 10^-3 mL = 5 mL = 5 x 10^-3 L

60000 uL = 60 mL = 6 x 10^-2 L
