In analysts are measuring chloride contents in water in four different laboratories. If known (accepted) value of chloride is 105 mg/L then results obtained in ______ laboratory have low accuracy and high precision.
Answer: 85.8mg/L, 86.7mg/L, 88.85mg/L, 87mg/L
Explanation
85.8 mg/L, 86.7 mg/L, 88.85 mg/L, 87 mg/L
These values are far from the accepted value (105 mg/L), so they have low accuracy.
They are very close to each other, so they have high precision.
Conclusion: Low accuracy and high precision.
