A 0.1% Methylene blue solution is needed for the detection AFB (Acid Fast Bacillus) in sputum smears. To prepare this, 1±0.03 grams of methylene blue is dissolved in a 1000±0.36 mL water. Determine the relative uncertainty of the solution. You will need to measure 30 mL of this solution using a pipette. You only have a Class B 10-mL pipette (±0.04mL) and a Class A 5- mL(±0.01mL) volumetric pipette. Is it more accurate to use the Class B pipette three times or the Class A pipette six times?
