### How many significant figures are in the measurement 33050 grams?

There are four significant figures in 33050. The trailing zero is not significant because there is no decimal. There would be five significant figures in 33050. If we were to remove the last zero in the number, we would alter the value of the number. Had the number been 3305.0, then there would have been four significant digits.

### What is an example for significant figures?

Significant figures are important for science, they tell how certain you are of a certain value. The rules for significant figures are as follows: If it is a decimal number, look at the first number on the left. If it is not zero, start counting the amount of numbers, and that's how many significant figures you have. For example, 7.495 has 4 significant figures. If it is zero, keep going until there is digit larger…

### How many significant figure for 2.9979 x 108?

5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)

### Explain why significant figures represent the precision of a measurement and not its accuracy?

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…

### How many significant figures are found in the value 5.5550x10?

Trailing zeros after a decimal point should be significant digits; otherwise, there would be no reason to write them. By this rule, the given number has five significant digits. Additional answer It is incorrect to put trailing zeros after the decimal digits because they have no meaning. Therefore there are four significant figures both before and after the multiplication by 10. That multiplication merely shifts the decimal point one place to the right without altering…

### How many significant digits are 0.1020?

0.1020 is a number to 4 significant figures. The rule is that "Zeros must be kept to show the position of the decimal point or to indicate that zero is a significant figure." Then the leading zero before the decimal point is retained as this shows the position of the decimal point. The zero between 1 and 2 is a key part of the number. The final zero (after 2) is a significant figure otherwise…

### How are significant figures defined?

A significant figure is one which has an impact on what you are calculating. They tend to come up where pure maths meets science. Normally you round to 2 or 3 significant figures because after that the tiny value represented by your rounding is pretty insignificant. You should however account for rounding errors in your final results accuracy.

### What is the value of 1467 when rounded to three significant figures?

If you are rounding a 4 digit number to 3 significant figures, then you're rounding to the nearest ten. The 4th digit is 7, so since this digit is >= 5, you should round up the 3rd digit. 1467 becomes 1470. In scientific notation you would express this as 1.47 x 103 to make it clear that there are only 3 significant figures.
