Question

what would be the benefit of taring the scale with the beaker? we can now easily determine the weight of the beaker without having to worry about the sodium chloride. no calculation is needed to determine the weight of the sodium chloride. there is no benefit.

Explanation:

Taring a scale with a beaker sets the scale's reading to zero with the beaker's weight accounted for. So, when adding substances like sodium - chloride, the scale directly reads the weight of the added substance without the need for subtracting the beaker's weight (i.e., no calculation is needed to determine the weight of the sodium chloride).

Answer:

B. No calculation is needed to determine the weight of the sodium chloride.
