Final answer:
The number of significant figures in 34 g is 2. The number 34 g has two significant figures, as it includes two non-zero digits with no additional digits or decimal points affecting significance.
Step-by-step explanation:
The number of significant figures in 34 g is 2. To determine the number of significant figures in a measurement, we look at the digits that are known with certainty and the first uncertain digit. In this case, both the digits 3 and 4 are known with certainty, so they are significant. All other digits are considered uncertain. Therefore, the measurement 34 g has 2 significant figures.
The number 34 g has two significant figures, as it includes two non-zero digits with no additional digits or decimal points affecting significance.
The number 34 g indicates two significant figures. Significant figures are all the nonzero digits plus any zero digits that are contained in between them or are final zeros to the right of the decimal point in a decimal number. In this case, the number 34 g has two non-zero digits, '3' and '4', and no additional zeros or decimal points to consider for significance. Therefore, it contains precisely two significant figures.
The number of significant figures in a measurement indicates the precision of the value. In the case of 34 g:
The number 3 is a non-zero digit and contributes to the significant figures count.
The number 4 is also a non-zero digit and adds to the count.
In the absence of a decimal point, trailing zeros after the last non-zero digit are considered placeholders and not counted as significant figures.
Therefore, in the measurement 34 g, there are two significant figures. The trailing zero in this context is not counted, as it serves as a placeholder to indicate the magnitude of the number but does not contribute to the precision of the measurement.
Understanding significant figures is essential for conveying the precision of a measurement. In this case, the mass is known to two significant figures, indicating that it was measured with a level of precision that allows for certainty in the tens place but not beyond. Scientists and researchers use significant figures to communicate the precision of their measurements and to perform accurate calculations based on those measurements.
