Assignment 3 – Numbers

Assignment due on Thursday Feb 1st. 10 hours from now

For this assignment make sure you use the correct number of significant figures and the correct conversion factors.

*You can upload a scan of an easy to read solution.*

*1.* Blood plasma is prepared and the density is checked for safety. It should be 1.025 g/cc ± 2%. The volume and mass of the prepared plasma is measured to be 100. ml ± 3% and 3.53 oz ± 1%. Calculate the density and the uncertainty in the measurement and determine if it safe to use. (Density= mass/volume)

*2.* *You are building a tank with a radius of 3’5” (3 feet 5 in) ±0.5” and a height of 8.5’ ± 2”.* *What is the volume and its uncertainty that the tank will hold?* *Give your answer in cubic feet and then convert both the measurement and its uncertainty to m3*

*(Volume of a cylinder = Area x height = * *2p radius x height* )
