Question

An experiment in your science class lists the materials needed for the lab. It is your job, as a lab partner, to measure out 25 mL of distilled water and 2.5 grams of magnesium. What lab measuring tools would you choose to measure each substance and how would you use each tool to get the correct amounts? Be sure to describe the process you would follow step-by-step.

Answer 1

 Overview: 
You would use a graduated cylinder to measure 25 ml of the liquid and use a scale to weigh the amount of Magnesium (it can be a balance but most labs now have small scales) and  you would carefully put small amounts of magnesium until it states 2.5 grams.

Procedure: 
Take the graduated cylinder and place it on the table. Carefully take the water and fill the graduated cylinder up to 25ml. If you took to much just simply pour some out and if you didnt take enough then put more. After you measured the water then you can pour the 25 ml of water into a beaker, but this is totally optional. 

For the magnesium first you put on the scale and set it to grams. Afterwards just take small pieces of the magnesium and place it on the scale until you reach 2.5 grams. Afterwards you can carefully place the magnesium in another beaker or something like that.
