How many significant figures should you report for an object weighing exactly 15 grams?
When reporting a measurement of 15 grams, it has two significant figures, as both digits (1 and 5) are non-zero and contribute to its precision. Since the number is presented without any decimal point, it implies that the measurement is exact to the nearest whole gram. Therefore, you should report the weight of the object as having two significant figures.
What is 1200 multiplied by 12?
14,400, but since 12 has only 2 significant figures, the answer should more properly be written as14,000
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.
When numbers are divided or multiplied the calculated result is rounded off to the same number or significant figures present in the factor with the least number of significant figures?
Yes. That's a step you should usually include, to avoid the result from looking more accurate than it actually is.
How many significant figures should be in the resulting calculations?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
If you multiplied 6774m by 46m how many significant figures should you report in your answer?
You should report your answer to three significant figures because 6774m has four significant figures and 46m has two significant figures, so the least number of significant figures between the two numbers determines the number of significant figures in the product.
How to find significant figures when multiplying numbers?
When multiplying numbers, count the number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures.
How do you multiply numbers while considering significant figures?
When multiplying numbers with significant figures, count the total number of significant figures in each number being multiplied. The result should have the same number of significant figures as the number with the fewest significant figures. Round the final answer to that number of significant figures.
Is 3.60 a greater decimal than 3.600?
3.60 and 3.600, as well as 3.600000000, are all identical in value.
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.
How many significant figures should you report for an object weighing exactly 15 grams?
When reporting a measurement of 15 grams, it has two significant figures, as both digits (1 and 5) are non-zero and contribute to its precision. Since the number is presented without any decimal point, it implies that the measurement is exact to the nearest whole gram. Therefore, you should report the weight of the object as having two significant figures.
When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.
What is 1200 multiplied by 12?
14,400, but since 12 has only 2 significant figures, the answer should more properly be written as14,000

What is the process for determining the correct number of significant figures in a calculation involving both addition and multiplication?
To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.
How many significant figures should be in the resulting calculations?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
