Calculations: Remember to use significant figures. Show all equations and figures used. UNITS must be included in all calculations. 1. Volume of a drop of oleic acid solution 2. Volume of oleic acid in the drop 3. Area of the Langmuir-Blodgett film...
Math in math class is the similar, but not the same as math in a science class. The rules of math don't change, but the applications are different. Significant figures are used in science-based mathematical calculations. Answer and Explanation: ...
(Sections 8.1 and 8.5) Report answers to calculations using the correct number of significant figures. (Section 8.2) Find the atomic mass for elements, the molecular mass for molecular compounds, and the formula mass for ionic compounds. (See Sections 9.2 and 9.3) Use the atomic mass for ...
Do all calculations to three significant figures. Calculate the following integral: ∫0π2[(2)hat(i)+(sinθ)hat(j)+(cosθ)hat()]dθShow all work There are 3 steps to solve this one.
Chapter 2 Lecture Basic Chemistry Fourth Edition Chapter 2 Measurements 2.4 Significant Figures in Calculations Learning Goal Adjust calculated answers. 1 Significant Digits Reflect the accuracy of the measurement and the precision of the measuring device. All the figures known with certainty plus one ex...
for the above type example, the 1,000,000 will mean something like 6 significant figures are likely to be lost in calculation.even bearing this in mind, the sort of iteration described above cannot simply continue until epsilon is met, because epsilon might never be met (eg use -9999999 ...
a brief introduction to using bc with files Using bc with files allows complex calculations to be repeated, again and again, a bit like using a spreadsheet to run the same calculations on changing figures ... but faster. Here is a simple example: scale=2 /* C-style comments are all...
Adding with Significant Digits ? The value with the fewest number of decimal places, going into the calculation determines the number of decimal that you should report in your answer. Adding with Significant Digits ? E.g. a) 13.64 + 0.075 + 67 ? b) 267.8 – 9.36 13.64 + 0.075 + 67 ...
Express your answer to three significant figures and include the appropriate A beam is under a distributed force as shown. The beam is made of A992 steel and has a square cross-section (width = height = 10 cm). Find the ...
Now work out the largest and smallest answers I could get: The largest: The smallest: Work out which one is further from the number only answer: So the total area is: To an appropriate number of significant figures it’s: b) This part of the problem is a division problem, since we ...
