How to express 27000000 using 1 significant figure?
The number 27000000 expressed using 1 significant figure is 3 x 10^7.
How many significant figures will the product of 0.1400 and 6.02 and 1023 have?
To determine the number of significant figures in the product of 0.1400, 6.02, and (10^{23}), we need to identify the significant figures in each number. The number 0.1400 has four significant figures, 6.02 has three significant figures, and (10^{23}) has one significant figure (as it is a power of ten). The product will have the same number of significant figures as the term with the least significant figures, which is 6.02 with three significant figures. Therefore, the final product will have three significant figures.
How many significant figures does this number have 18.20?
Four. When the decimal point is expressed, trailing zeros are significant.
How many significant figures in 2.8 x 10.5?
To determine the number of significant figures in the product of 2.8 and 10.5, we look at the number of significant figures in each number. The number 2.8 has 2 significant figures, and 10.5 has 3 significant figures. When multiplying, the result should be reported with the same number of significant figures as the factor with the least significant figures, which is 2. Therefore, the product of 2.8 x 10.5 should be expressed with 2 significant figures.
What is 62.125 kg rounded to two significant figures?
It is: 62 kg
What is the number of days in a year expressed in scientific notation with three significant figures?
The number of days in a year is approximately 365.25. In scientific notation with three significant figures, this can be expressed as 3.65 x 10^2 days.
What is the sum of 6.210 L and 3 L expressed in the correct number of significant figures?
9
What is the sum of 6.210L and 3L expressed in the correct number of significant digits?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
When the measured number of 0.0090 is mulitipiled by the measured number 87.10 the answer has two significant figures?
When multiplying numbers, the result should reflect the least number of significant figures in any of the factors. In this case, 0.0090 has two significant figures, and 87.10 has four significant figures. Therefore, when multiplying these two numbers, the result must be expressed with two significant figures, leading to a final answer that reflects this precision.
How many sig figs in the number 2300?
The number 2300 has two significant figures if it is written without a decimal point. If it is expressed as 2300. (with a decimal), it would have four significant figures. The presence of a decimal indicates that the trailing zeros are significant. Thus, the context of the number's presentation determines the count of significant figures.
What is the number of significant figure in avogadro's number?
Avogadro's number is typically expressed as (6.022 \times 10^{23}) and has four significant figures. The digits 6, 0, 2, and 2 are significant, while the exponent does not contribute to the count of significant figures. Thus, when using Avogadro's number in calculations, it's important to maintain these four significant figures for accuracy.
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 than zero, and start counting the numbers until the end. However many numbers there are, that's how many significant figures you have. For example, 0.000331 has 3 significant figures. If the number does not have a decimal, start from the right and if the number is not zero, start counting numbers and that's how many significant figures you have. For example, 93847 has 5 significant figures. If it is zero, the first significant figure will be the first non-zero digit. For example 3873000 has 4 significant figures. When you add or subtract some numbers, the amount of significant figures the answer should be expressed in depends on the number with the least amount of decimal places. For example, 4.398 + 5.2 = 9.6 You express the answer to the lowest number of decimal places a value you are adding or subtracting has. When you multiply or divide numbers, the answer is expressed to the lowest amount of significant figures that the values have. For example: 55 x 7 = 400 (when expressed with correct significant figures)
How do you put 20 in significant figures?
The number 20 can be expressed in significant figures depending on how precise you want it to be. If it is written as "20," it has one significant figure. If you want to indicate that both digits are significant, you can write it as "20." or "2.0 x 10^1," which shows two significant figures. The use of a decimal point or scientific notation clarifies the number of significant figures intended.
What is the product of the number 1000 and the measurement 0.003 57 m expressed in the correct number of significant digits?
The product of 1000 and 0.00357 is 3.57. The result should have three significant figures as that is the lowest number of significant figures given in the original numbers being multiplied.
