What precision of measurement can be expected from a multiple beam balance or a platform balance and from a digital balance? What precision of measurement can be expected from a 100-mL graduated cylinder and from a 100-mL beaker? Explain how you arrived at your answers.

Respuesta :

Among the instruments, both multiple beam balance and digital scale are used for the measurement of a solid and can be highly precise or consistent.  The multiple beam balance uses counterweights to determine the weight of the sample placed on a weighing pan.  It is the least accurate way of measurement since the readings do not include a decimal place. On the other hand, the digital scale is highly accurate and more precise than the multiple beam balance because it shows digits which are significant. However, the last possible decimal may be uncertain since it is probably estimated.

A 100-mL graduated cylinder is more accurate and moderately precise than a 100-mL beaker since the cylinder has lines between every whole number which indicate the decimal while the beaker hasn’t. 

The precision of measurement expected from a multiple beam balance is

  • moderate precision

The precision of measurement expected from a digital balance is :

  • Highest precision

The precision from a graduated cylinder is :

  • High precision

The precision from a beaker is :

  • moderate precision

Multiple beam balance and platform balance are used for the measurement of solid materials. They have a precision because they make use of counterweights to determine the weight of a solid sample. It is one of the least accurate form of measurement because it does not take into cognancy the decimal values in measurements. while

The digital balance is more precise than multiple beam because it takes into account the decimal values of measurement.

The precision from a 100 mL graduated cylinder is Higher than that of a beaker because a graduated cylinder can be used to take a more accurate measurement than a beaker.

Hence we can conclude that the answers to your question are as listed above.
