No. Stating more significant figures in a quantity doesn't guarantee that the figures are true.

3 significant figures

Five. All the zeroes after any nonzero digit are significant because they represent a measured or estimated quantity.

There are two types of significant figures, measured and exact. Numbers are often rounded to avoid reporting insignificant figures. Numbers can also be rounded merely for simplicity rather than to indicate a given precision of measurement.

The significant figures of a number are those digits that carry meaning contributing to its precision.

Significant figures indicate the precision of a measurement.

If the measurement was of such precision that the zero to the right of the 3 could be measured with accuracy, then it has two significant digits {30}.

4 significant figures.

A measurement that has a larger number of significant figures has a greater reproducibility, or precision because it has a smaller source of error in the estimated digit. A value with a greater number of significant figures is not necessarily more accurate than a measured value with less significant figures, only more precise. For example, a measured value of 1.5422 m was obtained using a more precise measuring tool, while a value of 1.2 m was obtained using a less precise measuring tool. If the actual value of the measured object was 1.19 m, the measurement obtained from the less precise measuring tool would be more accurate.

All three of them are significant figures

Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places

There are three significant figures.

The number of significant figures should be equal to the significant figures in the least precise measurement.

When divided by a calculator 45.67kg/3.42L equals 13.35 kg/L. Of the two quantities the highest common certainty we have is the 3 significant figures from the volume. Therefore the answer would be 13.4 kg/L rounded to three places.

370.0 has four significant figures, because the last zero indicates the precision of the number (to 1 decimal place).

There are two significant figures: 2 and 0 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 2) are not significant.

1 of them.

3 of them.

Science requires physical observation through measurement, which is always limited in precision hence significant figures. Mathematics, in contrast, deals with exact quantities represented by specific points on a number line, which implies infinite precision with infinite significant figures.

The trailing 0s are indicators of precision and so are significant figures. There are, therefore, 4 sig figs.

3.774 is to 4 significant figures (count them)

There a four significant figures in the number 16.82, the last '2' determines the best precision available.

There is one significant figure: 1 The significant figures of a number are those digits that carry meaning contributing to its precision. Leading zeros (the zero before the 1) are not significant.

There are three significant figures: the trailing zeros are significant because they are indicative of the precision of the number.
