Chapter 1, Problem 1.55E

Compare and contrast the multiplication/division significant figure rule to the significant figure rule applied for addition/subtraction in mathematical operations.

When a large or small number is written in standard scientific notation, the number is expressed as the product of a number between 1 and 10, multiplied by the appropriate power of 10. For each of the following numbers, indicate what power of 10 would be appropriate when expressing the numbers in standard scientific notation. a. 84,961,306 b. 0.4870 c. 0.000033812 d. 3,890,406,000,000

A two-gram sample of a red-colored liquid is found to have a volume of four cubic centimeters. Calculate the liquids density using the following uncertainty specifications, and express your answers in scientific notation. a. 2.00 g and 4.000 cm3 b. 2.000 g and 4.0 cm3 c. 2.0000 g and 4.000 cm3 d. 2.000 g and 4.0000 cm3

Consider multiplying “26.2” by “16.43.” What would a mathematician say the answer is? What would a scientist say? Justify the scientist’s answer, not merely citing the rule, hut explaining it.

A Chemistry 20 student uses a thermometer and a hot plate and measures the boiling point of ethyl alcohol to be 74.1 ºC. Then, she looks in a reference book and finds that the actual boiling point of ethyl alcohol is 78.4 ºC. What is her percent error?Record only your final answer with the correct number of significant digits and the proper units.

I DONT NEED A DIFFERNT ANSWER IM 100% SURE THAT BOTH OF THESE ANSWERS ARE CORRECT, i just need the steps of the calculation for both answers (100 and 8)

Charlotte is driving at 66.4mi/h and receives a text message. She looks at her phone and takes her eyes off the road for 4.30 seconds. How far has Charlotte reached in feet during this time?

A. Density Computation. Solve what is asked. Round off your answers into 2 decimal places and make sure to place the appropriate unit. Encircle your final answer.7. What volume (in cm3) of silver metal will weigh exactly 2500.0 g? The density of silver is 10.5g/cm3.

Bob and Jill are measuring the height of Mr. Chenet (Mr Chenet is 1.8593 meters tall). Bob gets a measurement of 1.6329, while Jill gets a measurement of 1.8. This means that Bob is more accurate, while Jill is more precise.  True or False?
