3. A mass spectrometer is an instrument that can be used to determine the mass of a substance. A student measured the mass of 3 samples. The expected mass was 568.4g. The 3 measurements were 548.5 g, 548.9 g, and 548.7 g. Is this random or systematic error

Respuesta :

The error that occurred is a systematic error.

What is random error?

Random error is a type of error that causes one measurement to differ slightly from the next.

What is systematic error?

Systematic error is a type of error that affects measurements in the same amount or by the same proportion, provided that readings are taken in the same way.

The three measurements 548.5 g, 548.9 g, and 548.7 g differ slightly but in the same amount and proportion.

Therefore, a systematic error occurred during the determination of the mass of the substance because the readings were taken in the same way and the measurement differ in the same amount.
