Mole Ratio Worksheet  All the following chemical reactions are balanced, please write your mole ratios like this 1:2, and ½ both ways.  This is important in the future.  Here’s a video in case you need help, or missed the lecture notes, lecture, and practice problems. https://www.youtube.com/watch?v=c9beXPzJ-Fs  Step 1) RTFQ- read the funny question, circle the known (what I know), and what you need (what I want to know).  Step 2) Set up DA, your KNOWN in the top left box, then cancel the units till you get the unit you want. Step 3) Do the math= calculate   __Zn + 2HCl  __ZnCl2 + __H2 balanced equation.a. How many moles of hydrogen are produced from the reaction of three moles of zinc?  1.Mole to mole prob, therefore set up mole ratio 2.Set up DA______________= 3.math How many moles zinc are needed to produce 3.5 moles of zinc chloride? Mole to mole prob, therefore set up mole ratio 1.Mole to mole prob, therefore set up mole ratio 2.Set up DA______________=           3.math How…

Moles, Mass and Number of Particles Activity Part A: Complete the chart by calculating the missing information. Use your orange Periodic Table and round significant figures accordingly. Pro tip! If you are using a calculated value in a subsequent calculation, keep at least an extra 2 significant figures in your calculation, and round your final answer.
