Please help with question 5 LChem 105 OnlineAt Home Buret1.2.3.4.5.Obtain the mass of a small beaker and record the mass to 0.01g.Fill your buret with water and note the starting volume in the buret. THISDOES NOT HAVE TO BE AT 0.0mL (the top).NOTE THE FOLLOWING!a. Burets read from OmL at the top and increase as you go down. This is sothe final volume during a process called a titration is larger and aids inthe subtraction to find the difference of solution added. DO NOTSUBTRACT READINGS FROM WHAT LOOKS LIKE THE FINAL MEASUREMENTON BURET.b.Your buret reads to the ones place. Therefore all your measurementsneed 1 decimal. We read to what we know and then estimate.c.Example: The buret to the right would have the following reading of 30.32mL(because it reads to the 30.X and you estimate one more digit because it isbetween 30.3 and 30.4 mL. Also note that I did not do any weird subtraction-it isread top down)Dispense 10 mL of water to the beaker by opening the stopcock of the buret andstopping when your reading is at 10mL more than what you started at.Mass the beaker and water.Dispense a new 10 mL of water and record the mass of water added.79.56g90.03g100.7310.471.

There are acouple of reasons you are being asked to do this:4. As a lab science class, you are expected to demonstrate mastery ofequipment use.10.75. I need to see that it is you doing to the lab.6. I also need to provide feedback on your measurements compared tothe actual reading. This is where significant figures come in.Be sure to use read feedback a-30!!! IMPORTANT!!
