Students have asked these similar questions
The density of a metal is 2.42 g/cm3. How many pounds are in 84.87 in of the metal?
(You can use the conversion factor approach. Or, you can convert density in g/cm3 to Ib/in3 and then multiply the result times number
of pounds.
2.52 cm = 1 inch
454 g 1 lb
Please see 'answers to extra problems' question 10 for hints on how to do this.)
You need to write your answer in the box with one number past the decimal.
Please don't worry about the sig figs in this case. In these formula problems, the Canvas software will give a variety of questions and
each student gets their data with different sig figs. So I just have to choose and sometimes it might seem that one past the decimal is
not the correct sig figs. Nonetheless. you have to follow that direction.

Using the data below (included for context), what is the equation for the trendline for the data points that fall in the linear range (linear range was found to be timepoints 1 min to 4 min,)? Your answer should be in the form of y = mx + b. Make sure that your trendline only includes the data points that fall in the linear range. In order to determine the trendline using Excel, you may need to create a new graph that only includes the earlier data points. With your new trendline, what is the initial velocity when 1 nM OXA-M290 is mixed with 60 μM nitrocefin? Make sure to include units in your answer.

- For these questions, be sure to apply the rules for significant figures. a You are conducting an experiment where you need the volume of a box; you take the length, height, and width measurements and then multiply the values together to find the volume. You report the volume of the box as 0.310 m1. If two of your measurements were 0.7120 m and 0.52145 m, what was the other measurement? b If you were to add the two measurements from the first part of the problem to a third length measurement with the reported result of 1.509 m, what was the value of the third measurement?arrow_forwardm means meter.
