Question

1. a student reports 12.345678 g using a balance measuring to 0.01 g. what is wrong?

Explanation:

A balance with a precision of 0.01 g can only measure and report mass values to the hundredths place (two decimal places). Reporting a value with six decimal places exceeds the instrument's measurable precision, as the balance cannot detect differences smaller than 0.01 g.

Answer:

The reported value 12.345678 g has too many decimal places. The balance only measures to 0.01 g, so the measurement should only be reported to two decimal places (e.g., 12.35 g).
