Question

floyd takes additional measurements of the mass of product formed in a reaction. he uses a balance that has smaller uncertainties than the first balance he used. what is floyd most likely trying to change? he is trying to increase his accuracy but not his precision. he is trying to increase his precision but not his accuracy. he is trying to decrease his precision and increase his accuracy. he is trying to increase his precision and decrease his accuracy.

Explanation:

Accuracy refers to how close a measurement is to the true value. Precision is about the consistency of repeated measurements. A balance with smaller uncertainties gives more consistent (precise) results. There's no indication that accuracy is being affected by just changing the balance with smaller uncertainties.

Answer:

B. He is trying to increase his precision but not his accuracy
